Green Silicon Carbide Chemical

The production method of green silicon carbide powder is basically the same as that of black silicon carbide, but the requirements for raw materials are different. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw materials, adding salt as an additive, and smelting in a resistance furnace at high temperature. The crystal refined by smelting has high purity and high hardness. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.
