Green Silicon Carbide is made from high-quality silica and petroleum coke as the main raw materials, with salt added as the additive and smelted by electric resistance furnace at high temperature. It contains more than 99% SiC, and it's harder, sharper, and more friable crystal than Black Silicon Carbide. The sharp, blocky grains of Green Silicon Carbide are highly pure and have extreme hardness (Mohs 9.4 /Knoop 2600), strong cutting capacity, excellent abrasion resistance, stable chemical properties, outstanding thermal conductivity, and high strength at high temperatures.
