Product Description
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 2670−2815 kg/mm2, micro−hardness is 2940−3300kg/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/ mm3 , natural bulk density is 1.2−1.6g/ mm3 , specific gravity is 3.20˜3.25g/ mm3. Raw material 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.
For wire-sawing of solar and semi-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, semi−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.
