Ceramics Grade Green SiC Powder

Green silicon carbide is made of petroleum coke and high-quality quartz sand as the main raw material and salt as additive. It is gotten by high temperature smelting of resistance furnace. Green SiC is of high purity and hardness, and its hardness is between fused alumina and diamond, and its mechanical strength is higher than fused alumina.

Application

1. Polishing ceramic and special steel glass, stone.

2. Cutting Solar Wafer, semiconductor silicon chip and crystal.

3. Raw materials for refractory products, engineering ceramics, heating elements, heat energy components and bonded abrasive tools.
