Characteristics and historyEdit
Tritanium, in its most stable form, has an atomic mass of 323, and was discovered by Humans and the Federation for the first time on planet Argus X on stardate 2261, in the early 23rd century. This element is part of the trans-uranic series of heavy elements. (ST reference: Star Fleet Medical Reference Manual)
Tritanium was of note to Federation science because of qualities as a strong metal when used in alloys and compounds. In ore could be found on many worlds, including discovery site Argus X. (ST reference: Star Trek Encyclopedia; TOS episode & novelization: Obsession)
Refined tritanium was used by many races and cultures for construction purposes. For example, the Federation and the Axanarri used tritanium for the hulls of starships while Cardassians used it in the construction of planetary facilities. (TNG episode: "Where Silence Has Lease"; VOY episode: "Repentance"; ENT episode: "Fight or Flight"; DS9 novel: Devil in the Sky)
Tritanium in ship construction requires care for optimal living conditions. In 2284, Torias Dax smelled that the the crew of USS Excelsior had recently scrubbed the ship's tritanium fixtures when he came aboard. (DS9 - The Lives of Dax short story: "Infinity")
In the 23rd century, the Federation obtained tritanium from a variety of sources across the Alpha and Beta Quadrants, including the mining facility on Angrena. (TOS - Star Trek: The Manga - Uchu comic: "Art of War") It was also mined on Hus-24. (TOS comic: "Husian Gambit")
In real-life science, element 126 has yet to be discovered. A placeholder name based on its number, "unbihexium", has been suggested to document the possible existence of this substance. Some models of theoretical science have stated that heavy elements on this scale may be impossible to synthesize or reproduce, and cannot exist in nature. Subspace science mentioned in Star Trek may account for the contradiction of this being a natural resource on other worlds.
