    Tantalum carbide (TaC) is an extremely hard (Mohs hardness 9-10) refractory ceramic material. The hardness is only exceeded by diamond. It is a heavy, brown powder usually processed by sintering, and an important cermet material. It is sometimes used as a fine-crystalline additive to tungsten carbide alloys. Tantalum carbide is recognized as the stoichiometric binary compound with the highest known melting point, at 4150 K (3880°C). The substoichiometric compound TaC0.89 has a higher melting point, near 4270 K (4000°C). It burns in air with a bright flash and only slightly soluble in acids.

    Tantalum Carbide Powder Applications

    1. Tantalum carbide is often added to tungsten carbide/cobalt (WC/Co) powder attritions to enhance the sintered structure's physical properties. It also acts as a grain growth inhibitor preventing the formation of large grains, thus producing material of optimal hardness.
    2. It is also used as a coating for steel molds in the injection molding of aluminum alloys. While providing a hard, wear-resistant surface, it also provides a low friction surface.
    3. Tantalum carbide is also used to produce sharp instruments with extreme mechanical resistance and hardness.
    4. It is also used in tool bits for cutting tools.
