Toranium
Toranium was a material produced by the Kobheerians which was in demand by the Cardassians, and was used in the construction of Terok Nor. Standard phasers were ineffective at cutting through toranium inlays and a bipolar torch was recommended. ()

In 2371, Commander Benjamin Sisko posed as a Kobheerian named Viterian, commander of the Rak-Miunis by using the 's holofilter. Sisko claimed to Gul Benil that he was in Cardassian space because he was taking Kobheerian toranium to Cardassia Prime for use by their military during his undercover mission to rescue Major Kira Nerys from the Obsidian Order.
