    What is tantalum carbide powder?

    tantalum carbide powderTantalum carbide (TaC) is an extremely hard (Mohs hardness 9-10) refractory ceramic material, commercially used in tool bits for cutting tools. 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 has the distinction of being 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. Has a metallic luster.

    When used as a mould coating, it produces a low friction surface.
    Tantalum carbide-graphite composite material, developed in Los Alamos National Laboratory, is one of the hardest materials ever synthesized.
    Dusts from grinding can be flammable.
    Substances to avoid are: flammable gases (dust may form explosive mixtures with gases)

    Tantalum Carbide Powder Typical Applications:

    • 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 moulding of aluminium 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.
