With good anti-oxidation, thermal conductivity and toughness, it is extensively used as key high strength, anti-corrosive, high temperature structural and welding thermal spray coating material. The fine ZrC powder is an important cermet material for cutting tool in hard alloy, atomic energy, electronic devices etc. Zirconium Carbide is also a kind of high melting point material with high hardness and excellent high temperature refractory, which can be used as a raw material of solid propellant in rocket motor for aerospace industry, raw material for the production of zirconium metal and zirconium tetrachloride, and other promising fine ceramic material.
