Silicon carbide (SiC) is using quartz sand and petroleum coke or coal tar, wood chips as raw material through high temperature electric resistance furnace smelting. Commonly known as carborundum. Pure silicon carbide is colorless transparent crystal. Industrial silicon carbide because of the variety and content of the impurities contained, and assumes the yellow, green, blue and black, transparency vary with the different purity. Silicon carbide crystal structure is divided into six party or rhombohedron of alpha SiC and cube of beta SiC (called a cubic silicon carbide). Silicon carbide industrial manufacturing method is with high quality quartz sand and petroleum coke refining in resistance furnace. Blocks of refined silicon carbide, crushing, acid and alkali washing, sieving and magnetic separation and wet separation and granular products
Silicon carbide has four main application fields, namely: Senior functional ceramics, refractories, abrasives, metallurgical raw materials. At present, the silicon carbide raw material has to a large number of supply, not high-tech products, and high technical content of nano-sized sic powder used for short periods of time can't form scale economy.
(1) as abrasive, abrasive tool can be used to do, such as grinding wheel, whetstone, grinding head, sand tile etc.
2 as a high temperature resistant materials and metallurgical deoxidizer.
(3) single crystals of high purity, it can be used in the manufacture of semiconductor, the manufacture of silicon carbide fibers.
