Grinding wheel uses silicon carbide 30# 36# 46# 60# black silicon carbide 98.5%
Grinding wheel uses silicon carbide 30# 36# 46# 60# black silicon carbide 98.5% Black silicon carbide grain is produced in an electric-resistance type furnace through fusing quartz sand and petroleum coke with high temperature. Its hardness is between fused alumina and diamond. It has higher mechanical intensity than fused alumina.Black silicon carbide micro powder for
