High quality green silicon carbide for ceramic sand wheel

Product: Green silicon carbide

Raw material: petroleum coke

Color: Green

Usage: Sand wheel making

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

Packing: 25kg/bag


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.
