Boron carbide is mainly used for carbon refractory antioxidant role can make the product densification prevent the oxidation of carbon in carbon refractory in ~ at the same time, and react to generate the columnar crystals, distributed in the matrix and the clearance of refractory, thereby the porosity is decreased, the increase in temperature strength, and the generated crystals, volume expansion, can heal volume shrinkage, reduce crack.

As one of the artificial abrasive materials, boron carbide has a Mohs hardness of 9.36, a microhardness of 43,149.26, 52955.95n/mm2, a specific gravity of 2.52g/cm3, a melting point of about 2450, which cannot react with acid and alkali solution. Boron carbide also has the characteristics of high chemical neutron absorption, non-magnetic semiconductor conductivity and high grinding efficiency.

Boron carbide is suitable for all kinds of cemented carbide cutting tool cutting precision components, such as mould etc. Grinding abrasive polishing, drilling and high-temperature refractory wear-resistant electrode material for making metal boride boron alloy boron steel engineering ceramics such as the main raw materials, manufacturing has been applied in recent years in the military field and space technology, is an indispensable material industry at present.
