What is silicon carbide material?

Silicon carbide, an inorganic material, is smelted from quartz sand, petroleum coke (or coal coke), wood shavings (table salt is required for the production of green silicon carbide) and other raw materials by high temperature smelting in a resistance furnace. Silicon carbide also exists in nature as the rare mineral, moissanite. In C, N, B and other non-oxide high-tech refractory raw materials, silicon carbide for the most widely used, the most economical one, can be called gold steel sand or refractory sand.?

Chinese industrial production of silicon carbide is divided into black silicon carbide and green silicon carbide two kinds, are hexagonal crystals, specific gravity of 3.20 ~ 3.25, microhardness of 2840 ~ 3320kg/mm2.

Silicon Carbide Application Fields

Silicon Carbide has four main application areas, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. Silicon carbide crude material has been able to supply a large number of high-tech products can not be counted, and the application of extremely high technical content of nanoscale silicon carbide powder for a short period of time is unlikely to form a large-scale economy.

1, as an abrasive, can be used to make abrasive tools, such as grinding wheels, oil stone, grinding head, sanding tiles, etc..

2, as metallurgical deoxidizer and high temperature materials.

3, high purity single crystal, can be used in the manufacture of semiconductors, the manufacture of silicon carbide fiber.

Main uses: for 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, quartz crystals and other wire cutting. Solar photovoltaic industry, semiconductor industry, piezoelectric crystal industry engineering processing materials.
