Introduction:

Silicon carbide has two common basic varieties of black silicon carbide and green silicon carbide, all of which are α-SiC. 

1.Black silicon carbide contains about 95% SiC, and its toughness is higher than that of 2.green silicon carbide. Green silicon carbide contains more than 97% SiC, and has good self-sharpness.

3.In addition, there is cubic silicon carbide, which is a yellow-green crystal made by a special process. 

Specification & Application:

1.Black silicon carbide: It is mostly used for processing materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals. 

2.Green silicon carbide:  It is mostly used for processing hard alloys, titanium alloys and optical glass. It is also used for honing cylinder liners and fine grinding high speed steel tools. 

3.Cubic silicon carbide: The abrasives made of it is suitable for super-finishing of bearings, and the surface roughness can be processed from Ra32 to 0.16 micron to Ra 0.04 to 0.02 micron.
