Green Silicon Carbide

It can be used for cutting and precision grinding of crystals, precision grinding of hard glass, slicing of single crystal silicon and polycrystalline silicon rods, precision grinding of single crystal silicon wafers, processing of super-hard metals, soft materials such as copper and copper alloys, etc. Processing of high-quality metals, processing of various resin materials, etc.

Green silicon carbide is made of petroleum coke and high quality silica as the main raw materials, adding salt as an additive, and smelting at high temperature in a resistance furnace. It is green crystal, brittle and sharp, and has certain thermal conductivity and electrical conductivity. The microscopic shape is hexagonal crystal, the Mohs hardness of silicon carbide is 9.3, the micro-density hardness is 2940-3300 kg/mm2, and the Knope hardness is 2670-2815 kg/mm2, which is higher than corundum and second only to diamond, cubic boron nitride and boron carbide in abrasive. The density is generally considered to be 3.20-3.25g /cm3. The natural packing density of silicon carbide abrasives is between 1.2-1.6g /cm3, and the specific gravity is 3.20-3.25g /cm3. The green silicon carbide powder produced by our company is made of high-quality large crystalline silicon carbide block by crushing and precision classification, stable quality, good crystallization, high surface cleanliness, no large particles, small fine particle content, concentrated particle size distribution, high grinding efficiency. Suitable for all kinds of precision grinding, the surface of the machined workpiece is uniform, no scratch. ...
