Tantalcarbide is a rare mineral of tantalum carbide with formula TaC. With a molecular weight of 192.96 g/mol, its primary constituents are tantalum (93.78%) and carbon (6.22%), and has an isometric crystal system. It generally exhibits a bronze or brown to yellow color. On the Mohs hardness scale it registers as a 6–7. Tantalcarbide is generally found in a granular state. It is extremely dense at 14.6 g/. Sub-conchoidal fracturing is exhibited. Specimens are extremely rare in nature. It is the only known mineral to exhibit the composition of TaC.

| - El tantalcarbur és un mineral de la classe dels elements natius. Va ser reanomenat l'any 1966 per per la seva composició químicaː tàntal i carboni. Originalment es creia que era tàntal natiu; la composició va ser verificada l'any 1962. (ca)

- Il tantalcarbide è un minerale scoperto in Russia sui monti Urali nei pressi di Nižnij Tagil e sui monti Altaj nel 1909 e classificato inizialmente con tantalio nativo. Nel 1962 si è scoperto che in realtà si tratta di carburo di tantalio. Prende il nome dalla sua composizione chimica (tantalio e carbonio). (it)

Sub-conchoidal fracturing is exhibited. Specimens are extremely rare in nature. It is the only known mineral to exhibit the composition of TaC. Tantalum carbide powder is used for many real world applications. Generally however it is not produced from the mineral tantalcarbide due to the rarity. Instead it is prepared by other means. (en)
