GREEN SILICON CARBIDE

When considering grinding hard materials, green silicon carbide must be on the list of alternative materials. Aluminum nitride ceramic is a new type of ceramic with high thermal conductivity, heat shock resistance, mechanical strength, and bending strength. Its hardness can reach 12Gpa, and the Mohs hardness is 7-8. Green silicon carbide is typically suitable for grinding materials such as jade, crystal, borosilicate glass, silicon wafers, optical glass, etc., with a Mohs hardness of 6.5-7. It shows that using green SiC 5micron for polishing aluminum nitride ceramic substrates and ceramic components can also achieve efficient grinding.

In the field of sapphire wafer polishing, the commonly used grinding material is boron carbide. However, the price of boron carbide is high, and for situations that require rapid removal, GC powder (Green silicon carbide powder) can also achieve the desired grinding effect.
