What is a green silicon carbide

Green silicon carbide and silicon carbide powder production is basically the same, just different requirements for raw materials. Green silicon carbide based petroleum coke and quality silica as the synthetic diamond raw material, add salt as an additive, smelting electric arc furnace, was smelted into cubic boron nitride purity crystals, hardness, hardness between corundum and diamond between mechanical strength higher than corundum.
