Product Parameters

Specification
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.

Performance:
1. Nano-boron carbide powder possesses high purity, small particle size distribution, high specific surface area;
2. Nano-boron carbide powder is a synthetic ultra rigid materials, the hardness is 9.46;
3. 56-6200Kg/mm2 microhardness, proportion was 252 g/cm3, melting is 2,250 degrees Celsius.

 

Product Application

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:
1. Nano-boron carbide powder also has more than micronstructured boron carbide powder higher neutron absorption efficiency,
thus widely applied to the industry and national defense industry;
2. Nano-boron carbide powder is not only applied in refractory materials, precision measuring element, and used in the manufacture
of precision nozzle, sealing ceramic products, fine works etc;
3. Nano-boron carbide powder is a synthetic superhard materials, as abrasive, high grinding efficiency, and not into the impurities,
is the ideal substitute of diamond abrasive;
4. Nano-boron carbide powder is a kind of high-grade refractory materials, was widely used in high precision engineering ceramic
nozzle, sealing, nuclear industry, national defense industry.
