Boron carbide is always used for the neutron absorption material, nuclear project ceramic product, seal ring, spray nozzle, bullet-proof vest, and the armor-plate board of tank and helicopter.

The main industrial countries have been paying attention to the research of bulletproof materials of boron carbide since twenty years ago. Nowadays the bulletproof materials of boron carbide are enormously applied to bullet-proof vest, and the armor-plate for tank and helicopter in some developed countries such as USA, Israel, South Korea as well as some other European countries.
