Green silicon carbide and silicon carbide production is basically the same, but different requirements for raw materials, the smelting of high purity into the crystal, hardness. Green silicon carbide suitable for grinding hard and brittle carbide and the metal and nonmetal materials, such as copper, brass, aluminum and magnesium and other nonferrous metals and gems, optical glass, ceramics until the non-metallic materials. Advanced ceramic materials are also ultra-fine powder. 
 1.) Key Features: packing density, grinding capacity, high hardness, cutting ability, concentration and uniform size distribution; high temperature, high strength, good thermal conductivity, impact resistance, for high-temperature indirect heating materials. 
 (2.) Adaptation: green silicon carbide abrasive widely used in a variety of industries, jade gem polishing, glass, steel, plastics, electronics, solar energy cutting, die casting, refractory,. Aerospace & Defense, building roads., The apparel industry (denim sandblasting), beauty tools, metal grinding, grinding of ceramic block is also suitable for the manufacture of abrasive grinding wheels. 
 (3) Physical Specifications: micro-shaped hexagonal crystals, silicon carbide is 9.5 Mohs hardness, Vickers micro hardness close 3000--3300 kg / mm 2 Knoop hardness is 2670-2815 kg / mm, micro hardness of 3300 kg per cubic millimeter. Higher than in the abrasive corundum and second only to the diamond, cubic boron nitride and boron carbide. Density is generally considered to be 3.20 g / mm 3, the natural packing density of silicon carbide abrasive green silicon carbide in the physical and chemical index of 1.2
