Black Silicon Carbide for Abrasives

Silicon Carbide is a non-metal mineral made of fusion of Quartz Sand and Anthracite/Petroleum Coke in electric resistance furnace under 1800 celcius degree. Because of different raw materials used, there are Black Silicon Carbide and Green Silicon Carbide. Black Silicon Carbide has high hardness, low expansion rate, good heat conductivity, widely used in abrasive tools, grinding and polishing of electronic parts, refractory materials, high end ceramics, foam ceramic, auto parts, aviation, deoxidizer etc.

Black Silicon Carbide Abrasives Grits is made according to China GB/Japan JIS/American ANSI/Europe FEPA standard and graded into material of standard particle distribution. It has higher hardness than Brown and White Fused Aluminium Oxide, while more brittle. It has higher toughness than Green Silicon Carbide. Our Black Silicon Carbide for Abrasives has little impurities, high toughness, coarse particles, good self-sharpening, good abrasion resistance and is an excellent abrasives.
