Black silicon carbide
Black, frangible and sharp, good thermal conductivity and electric conductivity.Microcosmic shape is a hexagonal crystal, Mohs hardness is 9.3, Vickers hardness is 2940-3300 kg/mm, microhardness is 2670-2815 kg/mm3. Among abrasives, silicon carbide's hardness is higher than corundum, and ranked below diamond, CBN and boron carbide. Density generally viewed is 3.20g/ mm3 , density of heap is 1.2-1.6g/ mm3 , specific gravity is 3.20～3.25. Raw material of green silicon carbide are petroleum coke and quality silicon sand, appended with salt, then smelt in electric arc furnace. Compared with green silicon carbide, the purity, hardness and brittleness of black silicon carbide are lower .
Main applications: solar wafer, semiconductor wafer and quartz chip wire sawing and lapping; bonded and coated abrasive tools; stone polishing; processing metal and non-ferrous metal with low tensile strength, such as gray pig iron, brass, aluminum, stone, leather and rubber.
