What is green silicon carbide?

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