Green silicon carbide powder as coating material of cylinder inner wall

Product: Green silicon carbide

Raw material: Petroleum coke

Color: Green

Usage: Coating material

Common size: 1-3 3-5 mm F 16-325 mesh

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
