 Zirconium carbide (CAS NO.12070-14-3) is a kind of hardness of the high melting point materials and excellent high-temperature refractories. Used in solid propellant rocket motor as a raw material. For the production of alloy steel.Also the production of metallic zirconium and zirconium tetrachloride raw materials, as well as the future of fine ceramic materials.It is also used as an abrasive, in metal cladding, in cermets, incandescent filaments and cutting tools.

Ignites in cold fluoride; chlorine (at 250°C); bromine (at 300°C); iodine (at 400°C). See also ZIRCONIUM COMPOUNDS.Safety information of Zirconium carbide (CAS NO.12070-14-3):
