Green silicon carbide for glass treatment
Description
The production method of green silicon carbide fine powder is basically the same as that of black silicon carbide, but the requirements for raw materials are different. 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.
