SILICON CARBIDE POLISH POWDER
1.The HRC of green silicon carbide is between the one of fused alumina and diamond;
2. Mechanical strength is greater than fused alumina;
3. High purity, Fragile. Hardness is 3288-3400 kg/mm2;
4. Physical properties of green silicon carbide is similar to black silicon carbide.
5. Good thermal conductivity and electrical properties.
Green silicon carbide (GC) is widely used to make coated abrasives or bonded abrasives. It also is used to produce advanced refractory products, electric products, electronic devices, etc.
The workable material by green silicon carbide grinding wheel:
1. Hard alloy, glass, ceramic and non-metallic materials;
2. Semiconducting material, high-temperature silicon carbide heating element, far infrared source base material, etc.
The company supply high quality top-grade green silicon carbide (sic 99%), the types are F-series (F12 to F1500), JIS-series (JIS240-JIS10000).
