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. 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.
