Emery, also known as carbon silicide, is bauxite, anthracite, iron sintered at high temperatures fused his high melting point, specific gravity, acid durability strong, interception capability is a new type of filter for sewage treatment material. Silicon carbide, also known as Moissanite. In contemporary C, N, B and other non-oxide refractory materials in high-tech, silicon carbide is the most widely used and most economical one. Can be called emery or refractory sand. Silicon carbide is with quartz sand, petroleum coke (or coal tar), wood (green silicon carbide need to increase the production of salt) and other raw materials in high temperature resistance furnace smelting. At present China's industrial production of silicon carbide is divided into two kinds of black silicon carbide and green silicon carbide, are hexagonal crystals, accounting for 3.20 to 3.25, microhardness 2840 ~ 3320kg/mm2. Pure silicon carbide crystals are colorless and transparent. Industrial silicon carbide due to the type and content of impurities contained different, and pale yellow, green, blue and even black, transparency varies with its purity. First, silicon carbide, silicon carbide industrial processes industrial production method is to use high-quality quartz sand and petroleum coke in a resistance furnace refining. Refining silicon carbide blocks obtained by crushing, acid washing, magnetic separation and screening or water-election into various size products. Second, Emery technical analysis of project data analysis project data AL2O3 98% density 3.95T/m3 SiO2 0.68% melting point 2050 ℃ Fe2O3 0.06% bulk density 2.5T/m3 three, carborundum (SiC) uses four major application areas of silicon carbide , namely: functional ceramics, advanced refractories, abrasives and metallurgical materials. SiC coarse material has been able to supply a large number, can not be considered high-tech products, while high-tech nano-silicon carbide powder is impossible to form a short application of economies of scale. ⑴ as an abrasive, can be used for abrasives, such as grinding wheel, Whetstone, grinding, sand tile and so on. ⑵ as metallurgical deoxidizer and high temperature materials. ⑶ high purity single crystal can be used for the manufacture of semiconductor manufacturing silicon carbide fibers. Main purpose: for 3-12 inch monocrystalline silicon, polycrystalline silicon, gallium arsenide, quartz and other wire cutting. Solar photovoltaic industry, the semiconductor industry, piezoelectric crystal engineering of industrial processing of materials. For semiconductors, lightning, circuit elements, high-temperature applications, UV detector, structural materials, astronomy, disc brakes, clutch, diesel particulate filter, filaments pyrometer, ceramic film, cutting tools, heating elements, nuclear fuel , jewelery, steel, protective gear, catalyst carrier body and other fields.
