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/cm^3. Sub-conchoidal fracturing is exhibited.
