TYPICAL SIZE F12 F14 grit silicon carbide for sandblasting abrasion test in Europe market

 

Brief introduction of black silicon carbide

 

Black Silicon Carbide is produced in a high temperature electric resistance-type furnace from a mixture of quartz sand and petroleum coke.

The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond.

Black silicon carbide’s mechancial intensity is greater than fused alumina, but brittle and sharp.

Black silicon carbide has some electrical and heat conductivity.
