Introduction to green silicon carbide:
Green silicon carbide is a kind of silicon carbide, all belong to α-SiC, green silicon carbide contains more than 97% SiC. Green silicon carbide is petroleum coke and silica as the main raw material, add salt as an additive, in the resistance furnace by high temperature smelting. It is green crystalline, brittle and sharp, and has thermal and electrical conductivity. Its density is generally considered to be 3.20-3.25g/cm3. green silicon carbide’s natural packing density is between 1.2-1.6g/cm3, specific gravity is 3.20-3.25g/cm3. microscopic shape of hexagonal crystals, Moh’s hardness of 9.2, Nup hardness of 2670-2815kg/mm2, Vickers hardness of 3000-3300kg/mm2. The hardness is 9.2 on Moh’s scale, 2670-2815kg/mm2 on Nulp scale, 3000-3300kg/mm2 on Vickers scale, which is higher than corundum and second only to boron carbide, diamond and cubic boron nitride in abrasives.
