What are the characteristics of carbide as well as its range of applications

 Green silicon carbide suitable for grinding and brittle metallic and non-metallic materials, such as copper, brass, aluminum and magnesium, and other nonferrous metals and  diamond blades gems, optical glass, ceramics until non-metallic materials. Ultrafine powder is  advanced ceramic materials.
1) Main features: high bulk density, grinding ability, high hardness, cutting ability, concentration and particle size distribution uniformity; has a high temperature, high strength, good thermal conductivity, impact, indirect heating materials for concrete blades  high temperature.
2) Adaptation: Green silicon carbide abrasive widely used in a variety of industries, jade gemstone polishing, glass, steel, plastics, electronics, solar cutting, die casting, refractories, Aerospace Defense, building roads, the apparel industry ( denim sandblasting), beauty tools, metal grinding, ceramic grinding block is also suitable for manufacturing abrasive grinding wheels.
3) Physical indicators: microscopic shape is a grinding wheels  hexagonal crystal, silicon carbide Mohs hardness of 9.5, micro Vickers hardness of 3000 density - 3300 kg / mm 2, Knoop hardness is 2670-2815 kg / mm, microhardness 3300 kg per cubic millimeter. In abrasive corundum, and ranked higher than diamond, cubic boron nitride and boron carbide. Density is generally considered to be 3.20 g / mm 3, silicon carbide abrasive natural green silicon carbide bulk density of 1.2 physical and chemical indicators.
