Black sic F180 F220 for sandblasting

Black sic F100 F120 F150

Production process and characteristics

Black sic F100 F120 F150 is brittle and sharp, and has high hardness, low expansion coefficient,good thermal conductivity and electrical conductivity. It takes petroleum coke and high quality silicon as raw materials, adds salt as additive, and is fused through the electric resistance furnace at high temperature. hexagonal crystalline of microscopic shape, 3300kg/mm³ of microhardness. Its hardness is higher than corundum but lower than diamond, cubic boron nitride and boron nitride among abrasives. Density is 3.2g/mm³, the natural bulk density of black silicon carbide abrasive is 1.2-1.6g /mm³, and the specific gravity is 3.20 – 3.25.
