Boron Carbide powder B4C
 Boron Carbide powder B4CIt is kind of black crystal materials, it is one of the hardest man- made materials. Its hardness with mohs hardness 9.36 and microscopic hardness 5400-6300kg/mm2 is only a little less than diamond, Its gravity density is 2.52g/cm3, melting point at 2450C.
Boron carbide possesses properties of endurance high/ low temperature, no reaction with either acids or alkais, the grinding efficiency is higher and with n magnetism. It is a good replacement of diamond. The powder of boron carbide is also well used for refractories industry, and also used for making high quality nozzle, etc.
