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. It has excellent abrasion
resistance and large neutron-absorbing cross section. 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 widely used in
machinery, electronics, instrumentation, metallurgy, national
defense, armed forces, nuclear, aviation industry, and also used
as abrasives, classic refractory and specific welding materials,
human protection materials and so on.
Boron carbide is widely applied as follows: boriding refractory,
ion transfusion, film layer as well as grinding, polishing,
lapping, drilling hard metal alloys, sapphire, watches, jewels,
etc. Meanwhile, it is main material for the wear-resisting parts,
precise meter-age element, sandblasting nozzle, 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 fields.
