Silicon carbide powder

Using JZFZ equipment for ultrafine grinding and grading of micron sized silicon carbide powder. Silicon carbide micro powder is mainly 1200 # and 1500 #, and domestic silicon carbide micro powder is mainly black silicon carbide micro powder and green silicon carbide micro powder.
2. Characteristics
Green in color, with a crystal structure, high hardness, strong cutting ability, stable chemical properties, and good thermal conductivity.
The microstructure is hexagonal crystal. The Mohs hardness of silicon carbide is 9.2, the Vickers microhardness is 3000-3300 kg/mm2, the Knoop hardness is 2670-2815 kg/mm, and the microhardness is 3300 kg/cubic millimeter. 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 g/mm3, and the natural packing density of its silicon carbide abrasive is between 1.2-1.6 g/mm3, with a specific gravity of 3.20-3.25. Green silicon carbide is mainly made from petroleum coke and high-quality silica, with salt added as an additive, and is smelted at high temperature in a resistance furnace. Its hardness is between that of corundum and diamond, and its mechanical strength is higher than that of corundum.

3. Purpose:
Used for wire cutting of 3-12 inch monocrystalline silicon, polycrystalline silicon, potassium arsenide, and quartz crystals. It is an engineering processing material for the solar photovoltaic industry, semiconductor industry, and piezoelectric crystal industry.
