Boron Carbide
Raw material and process of production:
Boron Carbide powder is one of the most hardness materials in the world. Its Mohs hardness is 9.3. B4C is with the properties of low density, high strength, high temperature stability and chemical stability characteristics. B4C is mainly used in wear-resistant materials, ceramics reinforced and grinding, polishing and drilling.

Main Application
For Nuclear Industry
B4C can be prepared into controlling bars, adjusting bars, accident bars, safety bars, screen bars, radiation resistant B4C tilts, plate, or neutron absorber(prepared with high B10 content powders),and radiation resistant layer for atomic reactor together with cement which is the most important functional component only next to reactor fuel.
Application of B4C in national defense industry
B4C can be used to produce bulletproof materials, such as bulletproof plate in bulletproof vests, ceramic bulletproof tile in military airplane pilot cabin and bulletproof plate in modern armored personnel vehicle and tank. It can also be used to produce the nozzles of gun and artillery in munitions industry.
For Other Engineering Ceramic Materials
B4C can be prepared into nozzles for sand spraying machine and high pressure water cutter, ring seal, mould for ceramics etc
For Refractories Industry
B4C can be used as anti-oxidation agent for low carbon magnesia carbon brocks and castables. It can be applied in key positions which suffer from serious erosion and high temperature, such as ladle, taphole(nozzle),sliding plate and stopper.
