silicon carbide ,green silicon carbide powder,sintered silicon carbide

Specifications

       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 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 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.
