Green Silicon Carbide also known as Green Carborundum is an extremely hard (Knoop 2600 or Mohs 9.2, microhardness 2940-3320) man made mineral that possesses high thermal conductivity (100 W/m-K). It also has high strength at elevated temperatures (at 1000°C, Green SiC is 7.5 times stronger than Al2O3). Among abrasives, silicon carbide’s hardness is higher than corundum, and ranked below diamond, cubic boron nitride and boron carbide. Density generally viewed is 3.20-3.25g/cm3, bulk density is 1.2-1.6g/cm3. 

▼Usage:
●The main use of grit size sand
As the abrasive, it is suitable for grinding carbide, hard and brittle metal and non-metallic materials, e.g. copper, brass, aluminum and magnesium metals, gems, optical glass, ceramics and other non-metallic materials.
Mainly used for glass polishing, crystal grinding, solar and semiconductor wafer wire sawing, ceramic polishing, as well as precision grinding wheel manufacturing, plastic products, etc.
●The use of green silicon carbide powder

Polish machine parts, metal products, cylinder, piston ring, pump, nozzles, bearings, roller ball and precision measuring instruments and polishing glass lenses, prisms, flat polished crystal and other products.

Silicon carbide powder is also widely used in refractory, wear-resistant floors, ceramic foam, special coatings, corrosion-resistant paint, flow separation and environmental protection industries.
