Green silicon carbide
Green, crystal structure, high hardness and strong cutting ability, stable chemical characteristics, good thermal conductivity. Microcosmic shape is a hexagonal crystal, Mohs hardness is 9.2., Vickers hardness is 3000-3300 kg/mm, microhardness is 3000-3300kg/mm3. Among abrasives, silicon carbides 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 3.203.25. Raw materiasl are petroleum coke and quality silicon sand, appended with salt, then smelted in electric arc furnace. Mechanical strength is higher than corundum.
Main applications: Solar and semiconductor wafer wire sawing; Crystal and ferrite polishing; Ceramic and special steel precision polishing; Bonded and coated abrasive tools; Cutting and polishing; Non-ferrous metal lapping such as glass, stone, agate and high-grade jewelry; High-grade refractory materials, engineering ceramic, heating elements and thermal elements.
