Black SiC Micro Grits FEPA "F"

Black Silicon Carbide (Black SIC) is produced in an electric resistance furnace from quartz sand and petroleum coke or anthracite at high temperature. The hardness and sharp particle of this material make it suitable for manufacturing of grinding wheels, superior refractory materials, lapping&polishing and abrasives blasting.
