Section 1: Substances and Phenomena

anesthezine gas

A gas the Circle's forces were going to flood the station's conduits with.
- "The Siege"

Sisko flooded the Defiant (except the engine room) with it to knock out the remaining Jem'Hadar.
- "One Little Ship"

Damar's plan to disable the minefield entailed reconfiguring the station's deflector array to emit an antigraviton beam.
- "Behind the Lines"

Used by the Cardassians to prevent DS9 from contacting Starfleet.
- "Emissary"

A substance; Quark's investment in some options on it was wiped out.
- "Business As Usual"

It can detect ships using a Romulan cloaking device. The Jem'Hadar used one to locate the Defiant.
- "The Search, Part I"

Remembering this, Sisko suggested it to the Cardassians when the Defiant was hijacked by Tom Riker.
- "Defiant"

A substance gouge-mined in the Clarius system.
- "The Nagus"

A Ferengi explosive, present along with sorium in the locator bomb used by Krax and Rom in an attempt to assassinate Grand Nagus Quark.
- "The Nagus"

A dangerous gas. Bashir was concerned about the rising levels in the station's air supply, though it was still well within safety margins.
- "Doctor Bashir, I Presume"

A substance which Alixus claimed was probably responsible for the neutralized EM readings on the planet where her colony was.
- "Paradise"

The metal of which Dax's bat'leth was made.
- "Blood Oath"

A mineral mined by a Vulcan geological survey on a planet in the Gamma Quadrant, which turned out to be the Hur'q homeworld.
- "The Sword of Kahless"

Kasidy said she would flood the Xhosa's hold with it as a precaution against possibly transporting goods with Temeklian virus.
- "For the Cause"

A rare crystalline element which in combination with an antimatter converter can be used as an energy source for a powerful explosive. Tahna Los dealt with Lursa and B'Etor for some, intending to use it to collapse the wormhole's entrance.
- "Past Prologue"

A substance on the planet where Sisko, Jake, Quark, and Nog went camping.
- "The Jem'Hadar"

It can jolt small ships which run into a pocket of it; there are such pockets in the Badlands.
- "Blaze of Glory"

A fertilizer. Zek offered 50,000 kilos to Bajor, in order to be allowed to conduct his business negotiations with the Dosi on DS9.
- "Rules of Acquisition"

Six transports of it were on the way; Dax notified Kira that they needed to find space.
- "Defiant"

A common chemical explosive. Neela used it in combination with infernite to bomb the DS9 schoolroom.
- "In the Hands of the Prophets"

A spray used to increase the size of katterpod beans, recommended by Kira's father.
- "Progress"

It is harmless to temporal beings, but deadly to the wormhole aliens. O'Brien was forced to modify the station so that it would focus one into the wormhole.
- "The Assignment"

A byproduct of the Defiant's Romulan cloaking device. They were lodged in the ship's ablative armor matrix, and, in combination with a microscopic singularity passing through Earth's system just as Sisko, Dax, and Bashir were beaming down, caused them to end up in 2024 Earth. The particles also created a subspace bubble around the Defiant which isolated it from the changes in the timeline. Kira and O'Brien used the remaining particles to search through different time periods for their missing crewmates.
- "Past Tense, Parts I and II"

A generator was rigged to cause a slow buildup of this in order to drive the Prophet and the pah-wraith away from the station without harming them.
- "The Reckoning"

The runabout carrying Sisko, Dax, Odo, and Garak back from a conference went through one.
- "Things Past"

A nerve agent, deadly to Cardassians although harmless to most other humanoid species. It can be synthesized from a combination of selenium and rhodium nitrite. Eddington's biogenic weapons spread it into the biosphere of Veloz Prime.
- "For the Uniform"

The space matter collected by the arva nodes in Tosk's ship.
- "Captive Pursuit"

A useful, relatively common mineral found in vast deposits on Torga IV. Sisko and an away team were conducting a mineral survey to determine the feasibility of a mining operation there.
- "The Ship"

It is also found on Kabrel II, among other places.
- "Statistical Probabilities"

The material of which the probe that brought "Pup" to the station appeared to be made.
- "The Forsaken"

The nebula where the commandeered Jem'Hadar warship crashed on a planet was one of these.
- "Rocks and Shoals"

A substance which has been known to turn viterium very unstable. Nog rigged torpedoes from the Valiant to deliver a burst of it to the Dominion battleship's antimatter storage system, but the tactic failed.
- "Valiant"

Absorbed by O'Brien in a conduit breach. Affected by the temporal displacement waves of a nearby quantum singularity (powering the warp core of a cloaked Romulan ship), they pulled him five hours into the future and back several times.
- "Visionary"

A rare substance needed by the Kobliads to stabilize their cell structures. The Federation is trying to provide it, though some Kobliads resort to stealing it. Seemingly it is dangerous to humanoid life in its raw form.
- "The Passenger"

O'Brien, with Jake's help, was in the process of converting ore processing unit 5 on DS9 to a deuterium refinery when the security program was triggered.
- "Civil Defense"

The metal that Ornithar thought Kira's earring appeared to be made of.
- "The Search, Part I"

The Breen had a dilithium mine in the Dozaria system, using survivors of the shipwrecked Ravinok as forced labor.
- "Indiscretion"

Dukat fooled the sensors of K'Temang's Bird of Prey into thinking the Groumall had refined dilithium crystal aboard.
- "Return to Grace"

A chemical energy source used in power generators, reactors, short-range transports, and in weapons (only when extremely pure). It was supplied to the Cardassians by the Valerians, who Kira suspected were still doing so.
- "Dramatis Personae"

An extremely strong alloy used in the construction of spacecraft and of many parts of DS9. Most scanners have trouble penetrating two meters thickness of it, which is the thickness of the plating of the access conduit above Quark's.
- "Captive Pursuit"

To destroy a Ketracel-white storage facility, a bomb consisting of this substance was planted inside an empty canister which was beamed down to the facility. See ultritium, below.
- "A Time to Stand"

A valuable substance recently and unexpectedly found on Parsion III.
- "Business As Usual"

golside ore

An ore which Dukat claimed the Bok'Nor had just delivered 14 metric tons of to the Regulon system before stopping at DS9.
- "The Maquis, Part I"

Part of DS9's tractor beam. It can shore up the structural integrity of a ship being held in it.
- "Captive Pursuit"

The station was threatened by a power drain which converted its power to gravitons; this was caused by what turned out to be an embryonic energy being.
- "Q-Less"

Sent out by the wormhole during its subspace inversion; it almost destroyed the Defiant.
- "The Visitor"

ion storm

A possible cause of the supposed "subspace interference" that prevented the Defiant from receiving Admiral Toddman's order to return to the station.
- "The Die is Cast"

It can be used to track a ship.
- "To the Death"

A rare mineral found in the burial vaults of the First Hebitian civilization on Cardassia Prime 200 years ago.
- "Chain of Command, Part II" [TNG]

A substance used in Cardassian ship construction.
- "The Maquis, Part I"

An illegal substance which Quark was going to smuggle to Orion on the way back from Earth. Its reaction to vented plasma from the warp core triggered a time warp.
- "Little Green Men"

A substance used in Cardassian warp engines. Boone told O'Brien that he was now running a ladarium mining sluice on Volan III.
- "Tribunal"

A rare, precious metal, which is liquid at room temperature. To give some idea of its value: just enough latinum to cover the bottom of a shot glass is equal to about 100 bricks. Liquid latinum is suspended inside bricks, bars, strips, and slips of gold (which is otherwise considered worthless in advanced societies), in order to make gold-pressed latinum, which is widely used as currency outside the Federation. Most transactions on DS9 are conducted with it.

1 million slips = 10,000 strips = 500 bars ("Body Parts"); therefore:
1 slip = 1/100 of a strip; 1/2000 of a bar.
1 strip = 100 slips; 1/20 of a bar.
1 bar = 2000 slips; 20 strips.

It's impossible for Federation transporters to beam through it.
- "Nor the Battle to the Strong"

A compound that will eat through duranium. Rom used it to get into Quark's latinum floor vaults, and also to open a panel in the wall of Vaatrik's former shop.
- "Necessary Evil"

Dax speculated that the renegade Jem'Hadar were using one to cover their tracks; it caused their ion trail to fade more rapidly than normal.
- "To the Death"

Kira picked it up from the Ravinok's damaged warp nacelle.
- "Indiscretion"

A synthetic composite used by the Federation in the construction of shield generators. Traces of it were found in the debris of the destroyed Bok'Nor.
- "The Maquis, Part I"

It was present in an energy barrier around a planet in the Rutharian sector. When scanned by the Olympia, it triggered a surge which disabled the ship's engines and caused it to crash on the planet. The radiation also somehow caused subspace signals to and from the planet to shift three years in time.
- "The Sound of Her Voice"

A mineral used as a power source. Grand Nagus Quark was to go to Stakoron II to negotiate for miszinite mining rights.
- "The Nagus"

Lauren mentioned that the deposits on Holna IV could run Dominion shipyards for years. (Spelled mizinite in the script.)
- "Statistical Probabilities"

A deadly gas. Dukat's security program included pumping it into the station's ore processor and the habitat ring to punish the revolting workers. In order to prevent this, Kira destroyed the station's life-support system.
- "Civil Defense"

Kira ordered it pumped into the air on all decks but the bridge, on the Jem'Hadar ship that she, Odo, Damar, Garak, and Rusot commandeered.
- "Tacking Into the Wind"

An extremely strong substance. The central structure of the site of the Iconian gateway on Vandros IV was composed of it; even a direct hit from a quantum torpedo wouldn't necessarily have destroyed it.
- "To the Death"

The cargo doors at Dominion Headquarters on Cardassia Prime were made of it.
- "What You Leave Behind"

An alloy used in the latest model tennis racket. Bashir sarcastically wondered if Tain wanted to know Bashir's opinion on it.
- "The Wire"

An extremely unstable and very rare substance, used in a microexplosive device planted in a power conduit behind the wall in Garak's shop.
- "Improbable Cause"

Extremely rare particles produced by certain matter/antimatter reactions. Dax and Odo found a concentrated field of them in a valley on a planet in the Gamma Quadrant. They eventually discovered that the particles were being used to create and maintain a village made up entirely of holograms.
- "Shadowplay"

A valuable mineral found in the Sappora system and on Timor II, among other places. Yanas Tigan owned a pergium mine.
- "Prodigal Daughter"

A type of beam used offensively by Jem'Hadar ships. It cut through the Odyssey's shields.
- "The Jem'Hadar"

A type of storm in space. DS9 was evacuated because of one, leaving only a skeleton crew.
- "Invasive Procedures"

It caused atmospheric interference on a moon in the Badlands, hampering communications, scanning, and transporter functions.
- "Heart of Stone"

Used by Kira to mask the engine emissions of the runabout she took from DS9.
- "The Darkness and the Light"

It is fatal to anyone exposed more than once. Starfleet Science believed that it would destabilize Changeling physiology, causing them to revert to their gelatinous state.
- "Apocalypse Rising"

A glowing mineral, which the geode Vash brought from the Gamma Quadrant resembled, but with a much higher molecular density and refraction index.
- "Q-Less"

The substance Seyetik used to reignite Epsilon 119.
- "Second Sight"

A bit of subspace flotsam picked up by a runabout turned out to be one. It was expanding, and endangered the station; however, life was detected in it, causing a dilemma over whether or not it should be destroyed. Finally Dax and Arjin were able to take it back where it belonged.
- "Playing God"

The Romulans power their warp cores with artificial ones. They are known to emit waves of temporal displacement which affect delta series isotopes.
- "Visionary"

A field generated by a prototype device developed by the Obsidian Order. Its purpose was to prevent Changelings from altering their biomolecular structure. Garak used it as a torture device against Odo while interrogating him for information on the Founders.
- "The Die is Cast"

Sisko and O'Brien considered injecting Odo with them so they could keep a transporter lock on him while he was in the Great Link, but O'Brien said they might disperse throughout it.
- "Broken Link"

A substance used in Cardassian ship construction.
- "The Maquis, Part I"

riddinite

The material of which the outside of the Albino's compound was built.
- "Blood Oath"

A substance, not very valuable, carried by a Bolian freighter which was captured by the Maquis. With rhodium nitrite, it can be reformulated and synthesized into cobalt diselenide.
- "For the Uniform"

A substance within a rogue comet that would cause a cascade reaction in the wormhole and collapse it permanently. A subspace field was used by Sisko and Kira to protect the wormhole from comet fragments; some leaked, however, igniting a subspace trail through the wormhole, which opened a line of communications through it for the first time.
- "Destiny"

Used as carrier waves.
- "Destiny"

spatial matrix

The beam fired from DS9's graviton emitters was supposed to collapse this inside the wormhole, but instead it was strengthened due to sabotage by the Bashir Changeling.
- "By Inferno's Light"

A rare anomaly which the Defiant was investigating with the aid of the Rubicon. It was thought that this study could lead to the formation of transwarp corridors. When the Rubicon reached the edge of the accretion disk, it and its crew began to shrink. To regain normal size, they needed to exit the anomaly the same way they entered.
- "One Little Ship"

One was created by the carrier wave in the wormhole, causing its gravity well to form unexpectedly.
- "Destiny"

The wormhole undergoes a natural one every fifty years; one occurred in 2372.
- "The Visitor"

A burst of polarized magnetic energy, usually produced by a damaged warp core. O'Brien detected one coming from Bopak III as he and Bashir were headed home.
- "Hippocratic Oath"

An anomaly that pulls matter into itself. The Hanoli system was destroyed by one. When Dax detected elevated thoron emissions near DS9, she thought it might be an incipient subspace rupture, whereupon it became one, thanks to aliens who were studying imagination by making it physical reality. Also known as a subspace rift.
- "If Wishes Were Horses"

A precious metal. A ring of pure surax was one of Quark's theoretical offers to Odo, who wasn't interested.
- "Q-Less"

One in the Denorios Belt damaged the Baraka, knocking it off course and propelling it into warp. It ended up in the Cardassian system, which was presumably how the ancient Bajorans had gotten there 800 years ago.
- "Explorers"

They are illegal anywhere except on the Tallonian homeworld. Regana Tosh was middleman for a Markalian smuggling operation dealing in them.
- "Hippocratic Oath"

A substance being shipped by Captain Jaheel to Largo V. He was anxious to deliver it before it spoiled.
- "Babel"

tetryon particles

They can exist only in subspace, and become unstable in normal space. High concentrations of them heralded the approach of the cloaked Romulan/Cardassian fleet to the wormhole.
- "The Die is Cast"

As far as Bashir could tell, the baby Changeling had been subjected to a massive amount of it.
- "The Begotten"

A thorium leak in the ore processor on Terok Nor in the mirror universe gave Bashir his chance to escape.
- "Crossover"

A substance stored in a cargo hold which a Circle search party was inspecting when they were captured by a team of station defenders led by Bashir, who warned them that prolonged exposure could have nasty consequences.
- "The Siege"

Emissions of a radioactive isotope. Elevated thoron emissions that came with an unknown alien race from the Gamma Quadrant were guessed by Dax to indicate a subspace rupture.
- "If Wishes Were Horses"

Used to block sensor scans.
- "Emissary"

Trinitrogen chloride, one of the components in plasma grenades, like the one used in an assassination attempt on Gul Dukat; it is also a cleaning solution which Timor, Jillur, and Ishan used while working for Quark.
- "Things Past"

The Rakhari name for a volatile gas found in the Chamra vortex. It explodes when disturbed by a ship moving too quickly or by weapons fire.
- "Vortex"

An extremely strong metal used in inlays in Cardassian-designed bulkheads. Phasers can't cut through it, but a bipolar torch can.
- "The Forsaken"

Sisko claimed to Gul Benil that the Defiant was the Rak'Miunis, shipping toranium to the Cardassians for military use.
- "Second Skin"

A mildly radioactive isotope used to detect where the graviton field was building up.
- "Q-Less"

trilithium isotopes

They are used in Romulan plasma torpedoes.
- "Image in the Sand"

A poisonous substance. Sisko used the Defiant's quantum torpedoes to spread it through the atmosphere of Solosos III.
- "For the Uniform"

A metal of which a statue sold at auction in Quark's was partially made.
- "In the Cards"

The metal of which O'Brien's EJ7 interlock was made.
- "In the Hands of the Prophets"

The Bajoran resistance had subdermal implants which they would activate if captured. The implants would release a trail of tritonium isotopes so that the person wearing the implant could be tracked and rescued. Kira located the Bajoran prisoners from the Ravinok by this method.
- "Indiscretion"

A substance formerly mined by the Dominion on the asteroid which is now the site of Internment Camp 371. See enriched ultritium, above.
- "In Purgatory's Shadow"

An explosive material formed into an earring which Kira wore into Dukat's quarters, intending to bomb them. It is difficult for Cardassian sensors to detect.
- "Wrongs Darker Than Death or Night"

An ore that used to be processed on DS9. It is very unstable, but needs a strong electrical charge to detonate it when in raw form. Sisko, O'Brien, and Jake used it to blow open a panel.
- "Civil Defense"

The part of the Ravinok's forward sensor array that Razka obtained was made of a uridium alloy, which indicated its Cardassian origin.
- "Indiscretion"

The subatomic particles that make up the wormhole and allow vessels to pass through it on impulse power.

A very strong, resilient alloy which becomes unstable when exposed to delta radiation. The antimatter storage system of the Dominion battleship encountered by the Valiant had support braces made of viterium. Watters and Farris hoped to exploit this weakness using torpedoes rigged to deliver delta radiation; but for some unknown reason the tactic didn't work, and the Dominion ship easily survived the resulting explosion.
- "Valiant"

Intendent Kira revealed to Sisko that Alliance ships have been known to chase them. The mirror Bashir and Dax used the information to fool the Alliance ships' targeting scanners.
- "Shattered Mirror"

A subspace tunnel between two points in normal space. One can use it to travel between those points almost instantly. Normal wormholes are unstable and do not last long. However, the Bajoran wormhole has been around apparently for at least 10,000 years. It is the only stable wormhole known to exist. Its ends, which are in the Alpha Quadrant near Bajor and in the Gamma Quadrant near Idran, are about 90,000 light years apart, a distance that would take 60-70 years to travel through normal space at warp 9. This wormhole, composed of verteron particles, is the artificial creation of a race of aliens who live inside it. Bajoran religion has embraced it as the "Celestial Temple". The wormhole is at bearing 157 mark 13 from DS9, 15 kilometers off the docking ring.

A subspace trail was created through it that made communications possible for the first time.
- "Destiny"

Every fifty years, the wormhole goes through a subspace inversion; one occurred in 2372.
- "The Visitor"

The wormhole's spatial matrix was strengthened by DS9's graviton emitters, due to sabotage; this ended the option of collapsing the wormhole to prevent Dominion invasion.
- "By Inferno's Light"

The wormhole apparently collapsed after a pah-wraith escaped into it; it was restored when the Prophets finally expelled the pah-wraith.
- "Tears of the Prophets", "Shadows and Symbols"

One of the active ingredients in Ketracel-white. It can be made by breaking down trinucleic fungus.
- "Statistical Probabilities"

A metal. The spatula Rom used as part of the circuitry in one of the holosuites was composed of a copper-ytterbium composite, which made it a perfect plasma conductor.
- "Our Man Bashir"
