Silicon Carbide
Introduction:
Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics which are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light emitting diodes and detectors in early radios were first demonstrated around 1907, and nowadays SiC is widely used in high-temperature/high-voltage semiconductor electronics. Large single crystals of silicon carbide can be grown by the Lely method; they can be cut into gems known as "synthetic moissanite". Silicon carbide with high surface area can be produced from SiO2 contained in plant material.
 
Black silicon carbide
Black silicon carbide is produced at high temperature in an electric resistance type furnace with quartz sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and sharp and heat conductivity in some degree. The abrasive made of it are suitable for working on cast iron, non-ferrous metal, rock, leather, rubber, etc It is also broadly used as refractory material and metallurgical additive.

Green Silicon carbide( abrasive material)
Green Silicon carbide crystaline block is made of petroleum coke,high-quality silica and common salt as additive through the smelting processing in the high-temperature resistance furnace.it is between corundum and diamond in hardness,and it is better than the corundum and diamond in hardness,and it is better than the corundum in mechanical strength,as it is crisp and sharp.
Usages:
It can be used as abrasives for grinding wheels,sand paper,sand belts and other abrasive tools to cut abrasives ,crystal refractories and electronic parts,etc.
