Application of green silicon carbide in wear-resistant industry
Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. It is green crystal, brittle and sharp, and has certain thermal and electrical conductivity. The microscopic shape is hexagonal crystals, and the Mohs hardness of silicon carbide is 9.4.
Due to the high hardness of green silicon carbide (Mohs hardness 9.4), it has irreplaceable advantages in many fields, such as the production of oilstone grinding stones, the production of ceramic films for environmental protection, and diamond tools. Green silicon carbide is needed for the production of grinding discs, the production of Teflon coatings, the production of wear-resistant layers for aircraft engines, and the surface wear-resistant layers of brake shoes for various motor vehicles
