Green, crystal structure, high hardness and strong cutting ability, stable chemical characteristics, good thermal conductivity. Microcosmic shape is a hexagonal crystal, Mohs hardness is 9.3., Vickers hardness is 2940-3300kg/mm2, Vickers microhardness is 2670-2815kg/ mm2. Among abrasives, silicon carbide's hardness is higher than corundum, and ranked below diamond, CBN and boron carbide. Density generally viewed is 3.20-3.25g/ cm3, natural bulk density is 1.2-1.6g/ cm3 , 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.
Application
For wire-sawing of solar and simi-conductor
Usage:
Green silicon carbide is used for wire-sawing of monocrystal silicon, polocrystalline silicon, potassium arsenide, quartz crystal, etc. It is the engineering processing material in solar photovoltaic industry, simi-conductor industry and piezoelectric crystal industry.
Feature:
1. High purity and large crystal silicon carbide ingots ensure the excellent cutting capability and stable physical condition,
2. Grains are isometric with sharp edge, which ensure the even self-sharpening capability as cutting material and minimum TTV of the products been cutted.
3. Particle size distribution is narrow and even.
4. High heat-resisting and refractoriness under load guarantee the small wire expansion in processing, suitable to all kinds of wire saw machine.
5. Grain surface possessed specially, micro-powder with clean surface and easily fit cutting fluid, such as polyethyleneglycol and so on.
