It is a good partner of the chemical industry because of stable chemical performance, boron carbide and alkali acid solution can not react, with high chemical level, so it is widely used in the production of other boron containing materials, such as zirconium boride, titanium boride, etc.

Boron carbide as additives in the product antioxidant effect, can make the product densification, prevent the oxidation of carbon in carbon refractory, during 1000 ~ 1250 at the same time, the reaction of Al2O3 and B2O3, generate 9 Al2O3 · 2 B2O3 columnar crystals, distributed in the matrix and the clearance of refractory, thereby the porosity is decreased, the increase in temperature strength, and generate 9 Al2O3 · 2 B2O3 crystals, volume expansion, can heal volume shrinkage, reduce crack.
