Introduction of Silicon Carbide Powder and Manufacturers

Silicon carbide powder looks green, and has crystal structure, high hardness, strong cutting ability, stable chemical properties and good heat conduction performance. The microscopic shape looks like hexagonal crystal. The Mohs hardness is 9.2, Williams microhardness about 3000-3300 kg/mm, Knoop hardness about 2670-2815 kg/mm, and the microhardness at 3300 kg per cubic millimeter.

In abrasive grains, silicon carbide is higher than corundum, and second only to diamond, cubic boron nitride and boron carbide. The density is thought to be 3.20 g/mm. The natural bulk density of silicon carbide abrasives is between 1.2 g/mm and 1.6 g/mm, and the specific gravity is 3.20 ~ 3.25. Green silicon carbide is obtained through high temperature electric resistance furnace smelting petroleum coke and high quality silica as the main raw materials and adding salt as the additive. Its hardness is between fused alumina and diamond, and mechanical strength is higher than fused alumina.

The physical properties of silicon carbide are quite different from silicon. Monocrystalline silicon carbide has more excellent physical properties than monocrystalline silicon, such as tenfold electric field intensity, threefold thermal conductivity, threefold forbidden band width, and double saturation drift velocity.

In addition, on the specific applications, although the technology of silicon carbide device is more difficult than monocrystalline silicon, but once the problem of process is solved, silicon carbide device will become ideal semiconductor materials in the 21st century, because of its short manufacturing process, small volume weight, the characteristics of oxidation resistance, long service life, high output power, etc. And the electric energy consumption of silicon carbide materials is extremely low, and an ideal energy-saving materials.

There are two silicon carbide manufacturers that are popular with buyers in the market, which can supply great quality silicon carbide and offer professional services for buyers: Qinyang Sanhui Refractory Material Co.,Ltd. and Yichuan Dongfeng Abrasives Co.,Ltd.
