Green silicon carbide

Green silicon carbide is green, containing more than 97% SiC, crystal structure, high hardness, strong cutting ability, stable chemical properties, good thermal conductivity.

The microcosmic shape is hexagonal crystal, the mohs hardness of silicon carbide is 9.5, the microhardness is 3280--3400kg/mm2, and the specific gravity is 3.20 ~ 3.25. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum. Green silicon carbide is made of petroleum coke and high quality silica as main raw materials, adding salt as additive, and smelting by resistance furnace at high temperature.

Main applications: solar wafer, semiconductor wafer, quartz chip cutting and grinding; Polishing of crystal and pure grain iron; Precision polishing of ceramic and special steel; Consolidation and coating abrasives, cutting, free grinding and polishing; It can also grind glass, stone, agate, fine jewelry and other non-metallic materials, and can produce high quality refractory materials, engineering ceramics, heating elements and thermal energy elements.
