Tantalum carbides are extremely hard, brittle, refractory ceramic materials with metallic electrical conductivity.
They appear as brown-gray odorless or dark to light brown powders which are usually processed by sintering. Being important cermet materials, tantalum carbides are commercially used in tool bits for cutting applications and are sometimes added to tungsten carbide alloys. The melting points of tantalum carbides peak at about 3880 °C depending on the purity and measurement conditions; this value is among the highest for binary compounds. Only tantalum hafnium carbide has a distinctly higher melting point of about 4215 °C, whereas the melting point of hafnium carbide is comparable to that of TaC.

Applications: For tantalum metal billets and powder, tantalum carbide, ceramic capacitors and additive in special optical glass.
Tantalum carbide is often added to tungsten carbide/cobalt (WC/Co) powder attritions to enhance the physical properties of the sintered structure. It also acts as a grain growth inhibitors preventing the formation of large grains, thus producing a materials of optimal hardness.

It is also used as a coating for steel moulds in the injection moldings of aluminum alloys. While providing a hard, wear resistant surface, it also provides a low friction mould surface. Tantalum carbide is also used in the production of sharp instruments with extreme mechanical resistance and hardness. It is also used in tool bits for cutting tools.
