The hardness of boron carbide is second only to diamond and cubic boron nitride in nature. It has the characteristics of high melting point, high hardness, low density, good wear resistance, and good neutron absorption capacity. It is widely used in refractory materials, engineering ceramics, nuclear industry, aerospace and other fields.

At present, alumina, silicon carbide and boron carbide are the main structural ceramics used for bulletproof ceramics. Among them, boron carbide is the armor material with the best bulletproof performance, and is currently used as aircraft armor material and special purpose protection structure.

In recent years, people of boron carbide ceramics research depth and strength increasing, in addition to the high purity and ultrafine boron carbide powder synthesis new methods constantly emerging, people are more committed to develop advanced practical forming process and sintering process technology research, so that the boron carbide products can be further industrialization in some high-tech fields.
