Green silicon carbide

[Product Specifications]: F8-F2000

[Production capacity]: 30,000 tons

[Scope of application]: Can be used for crystal cutting and precision grinding, 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, copper and copper alloys Processing of high-quality metals, processing of various resin materials, etc.

【product description】:

Green silicon carbide uses petroleum coke and high-quality silica as the main raw materials, adds table salt as an additive, and is smelted in a high temperature furnace. It is green crystal, brittle and sharp, and has a certain thermal conductivity and electrical conductivity. The micro shape is hexagonal crystal. The Mohs hardness of silicon carbide is 9.3, the micro hardness is 2940-3300 kg / mm2, and the Knoop hardness is 2670-2815 kg / mm2. It is higher than corundum in abrasive, second only to diamond and cubic. Boron nitride and boron carbide. The density is generally considered to be 3.20-3.25 g / cm3. The natural bulk density of silicon carbide abrasive is between 1.2 and 1.6 g / cm3, and the specific gravity is 3.20 to 3.25 g / cm3. The green silicon carbide micropowder produced by our company is selected from high-quality large crystalline silicon carbide blocks that are crushed and precisely classified, with stable quality, good crystallization, high surface cleanliness, no large particles, less fine content, concentrated particle size distribution, and grinding efficiency high. Suitable for a variety of precision grinding processes, the surface of the processed workpiece is uniform, without scratches. ...
