Product Description

Boron Carbide Powder (B4C) 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 is 2.52g/cm3 and melting point is 2450ºC, 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 special properties of light quality, neutron absorbing, semi-conductivity, etc., so it is used for armed forces and nuclear industry.

Boron carbide is widely applied as follows: boriding refractory, ion transfusion, film layer as well as grinding, polishing, drilling hard metal alloys, jewels, etc. Meanwhile, it is main material for the wear-resisting parts, precise meter-age element, precise spray nozzle, sealed washer, smelting boron steel, boron alloy, etc.

Boron carbide has showed many better properties of physics and chemistry in the hi-science/technology field.
