Silicon carbide powder: Features green, crystal structure, high hardness and cutting ability, chemical stability, good thermal conductivity. The microscopic shape of a hexagonal crystal silicon carbide of a Mohs hardness of 9.2, and a Vickers microhardness of 3000 - 3300 kg / mm 2, and the Knoop hardness of 2670-2815 kg / mm, and the microhardness of 3300 kg per cubic millimeter. Higher than corundum, second only to diamond, cubic boron nitride and boron carbide abrasive. The density is generally considered to be 3.20 g / mm 3, silicon carbide abrasive natural bulk density in the range of 1.2 - 1.6 g / mm 3, a specific gravity of 3.20 to 3.25. Green silicon carbide based on petroleum coke and quality silica as the main raw material, add salt as an additive in electric arc furnace smelting. Its hardness between corundum and diamond, the mechanical strength is higher than corundum. Edit this paragraph the main purpose for 3-12 inch monocrystalline silicon, polycrystalline silicon, GaAs, quartz crystal wire cutting. Solar photovoltaic industry, the semiconductor industry, piezoelectric crystal industry engineering processing materials. The silicon carbide main analysis methods: the content of silicon in the silicon carbide determine the hardness of silicon carbide. Wire cutting a great influence on the particle size of silicon carbide, but the most important is the shape of the silicon carbide particles. Free state cutting wire cutting silicon carbide particle shape change on the cutting efficiency and cutting quality. Detection methods: the content of silicon atomic absorption detection (detection efficiency, the value is more accurate). Silicon carbide particle size particle analyzer requires resistance method (high efficiency). Silicon carbide grain type detection Reith RA200 particle analyzer (a more accurate analysis of particle shape coefficient roundness) the domestic silicon carbide black silicon carbide powder and green silicon carbide powder. Silicon carbide powder Standard: GB, Japanese standard, European standard. GB and the standard for the mainstream in the market, while export Japanese standard-based.
