Boron Carbide (B4C)
Boron Carbide (B4C) Powder for Technical Ceramic Parts, blasting
nozzles, nuclear reactor, abrasive
We are the one of major supplier and exporter of Boron Carbide in
China.
Boron Carbide (B4C) is one of the hardest man-made materials in the
world. Its hardness is as high as 9.36 Mohs, its density is 2.52
g/cm3 and melting point is 2450℃. It possesses properties of high
strength, low density, corrosion resistant, low/high temperature
resistant, low thermal conductivity, high modulus of elasticity, no
magnetism and high grinding efficiency. It is a high performance
abrasive material and engineering ceramics material.
