Boron carbide, a black crystal powder, is one of the hardest Man-Made materials, its hardness with Mohs hardness 9.36 and microscopic hardness 5400-6300kg/mm2 is only near upon diamond, its density 2.52g/cm3 and melting point at 2450,The boron carbide possesses properties of endurance hi/low temperature, no reaction with either acids or alkalis, high grinding efficiency, no magnetism. It is a good replacement of diamond. Boron carbide also possesses the specialty properties of light quality, neutron absorbing, semi-conductivity, etc. so it is used in armed forces and nuclear industry.
