Pickling moisture level green silicon carbide micro powder 6000 mesh jewelry jade polishing disc for fine polishing

  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. The hardness

It is between corundum and diamond, and its mechanical strength is higher than that of corundum. Green silicon carbide is petroleum coke and high quality silica as the main raw materials, adding salt as Tim

Added, through the resistance furnace high - temperature smelting.

Main applications: solar wafer, semiconductor wafer, quartz chip cutting and grinding; Polishing of crystal and pure grain iron; Fine ceramic and special steel

Dense polishing; Consolidation and coating abrasives, cutting, free grinding and polishing; Can also grind glass, stone, agate and fine jewelry and other non-metallic materials

And can manufacture advanced refractory materials, engineering ceramics, heating elements and thermal energy elements.
