Product Description

Boron Carbide Powder (B₄C)  is one of the hardest materials people know. Its hardness with Mohs hardness 9.36 and microscopic hardness 5400-6300kg/mm2 is upon diamond nearly.
Its density is 2.52g/cm3 and melting point is 2450ºC.
 

 

Product Description

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.

Application

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.
