Tantalum carbide have high chemical stability and favorable high-temperature character . it is hard and heavy . Fine Tac powder is an important cermet material.

Application

Tantalum carbide (TaC) is an extremely hard (Mohs hardess 9-10) refractory ceramic material, commercially used in tool bits for cutting tools. The hardness is only exceeded by diamond.

It is sometimes used as a fine-crystalline additive to tungsten carbide alloys. Tantalum carbide is often added to tungsten carbide/cobalt (WC/Co) powder 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 alu minum alloys. While providing a hard, wear resistant surface, it also provides a low friction mould surface.
