Detailed Product Description

Boron Carbide, a black powder, is the hardest of the
conventional abrasives, Its Mohs hardness is 9.36,
melting point 24500c, density 2.51g/cm³.
It has following unique features: neutron absorbing,
of semi-conductivity, low thermal conductivity, high
grinding efficiency and no reaction with either acids
or alkali etc. Boron carbide is widely used to grind
and polish hard metal alloy, super-hard metal, high
carbide steel, jewel, hard ceramic and other hard materials,
to manufacture wear-resisting parts, metal cutting tools,
nozzles and neutron-absorbing rods, used as metal additive for
compound materials for military planes and as raw materials
for metal boride, metal ceramic, boron steel, boron alloy and
for special welding and refractory materials.
