Carborundum, also known as SIC, is made of quartz sand, petroleum coke or coal coke, wood chips, green silicon carbide produced by adding salt and other raw materials through resistance furnace high temperature smelting. Silicon Carbide is also a rare mineral found in nature, moissanite. Silicon Carbide, also known as carborundum. Among the non-oxide high-tech refractory materials such as C, N and B, Silicon Carbide is the most widely used and the most economical one, which can be called Jingang sand or refractory sand. At present, the silicon carbide produced in China is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals with specific gravity of 3.20 ~ 3.25 and microhardness of 2840 ~ 3320kg / MM2.
Silicon Carbide has four main applications, namely functional ceramics, advanced Refractory, abrasives and metallurgical raw materials. Silicon Carbide coarse material can be supplied in large quantities, and can not be regarded as high-tech products. However, the application of nanometer silicon carbide powder with extremely high technology content is unlikely to form economies of scale in a short time. As an Abrasive, can be used to do abrasives, such as grinding wheel, whetstone, grinding head, emery tile and so on. As a metallurgical deoxidizer and high temperature resistant material. High Purity single crystal, can be used for the manufacture of semiconductor, the manufacture of silicon carbide fiber. Main uses: used for 3-12 inches monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystal and so on line cutting. Photovoltaics, Semiconductor industry, piezoelectric crystals, engineering materials.Steelmaking Deoxidizer Made in China
