Black silicon carbide

[Product Specifications]: F8-F220

[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, etc. Processing of high-quality metals, making consolidated and coated abrasives; grinding and polishing.

【product description】:

Black silicon carbide uses quartz sand and petroleum coke as the main raw materials and is smelted in a high temperature furnace. It is black 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 abrasives and second only to diamond. , 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. ...
