Description: Boron carbide, with black
crystal powder form, is one of the hardest man-made materials. It has MOHS hardness of 9.36 and microscopic hardness 5,400 - 6,300kg/mm2, which is next to diamond. Its density is 2.52g/cbm and the melting point is 2,450oC.
The boron carbide is with high and low temperature resistance, and high grinding
efficiency, without reactions to either acid or alkalis. It's not magnetic, and is a
good substitute for diamond.
Boron carbide is of
light weight, with neutron absorbing function and semi-
conductivity so that it is used in the military and nuclear industries in addition to
boride refractory, ion transfusion, and
film layer usage.
Furthermore, it can be used for grinding, polishing, and drilling hard
metal alloys
and jewels. It is the main material for wear-resistant parts, precise
meter elements,
precise spray nozzles, sealed washer smelting boron
steel and boron alloys.
Boron carbide is with various excellent physical and
chemical prosperities, suitable
for the high-tech industries.
