High quality green silicon carbide for ceramic sand wheel
Description
Green silicon carbide uses petroleum coke and high-quality silica as the main raw materials, and adds table salt as an additive. It is smelted through a high-temperature resistance furnace. The smelted crystal has high purity and high hardness. Its hardness is between corundum and diamond. Mechanical strength Higher than corundum.
