Green SiC powder for granite grinding

Green SiC is an excellent abrasive powder with extremely high hardness. It works perfectly for granite grinding.  Aluminum oxide and silicon carbide are both commonly used abrasive media for etching and grinding stone materials such as marble, concrete, and granite. However, there are some differences between those applications.

Marble often gets lower hardness (Mohs 4-4.5)than granite and glass. Aluminum oxide is good enough for blasting on marbles. Black silicon carbide is also widely used for marble grinding. However, Granite is formed from a volcanic eruption. It is an outstanding material for outdoor building decoration. Granite is much tougher than marble with a Mohs hardness of 6-7. Thus it is more difficult to grind and polish granite. So there is high demand for granite grinding media. Green silicon carbide is just for that usage.

Green silicon carbide abrasive powder not only can work as blasting media on Granite. But also it can make granite grinding wheels & granite polishing blocks. With various grit sizes, green silicon carbide grain F60,F120, F180 is always for Oxalic acid polishing block. Green silicon carbide powder F240,F280,F600,F800,F1200 grits are suitable for making diamond polishing wheel for grainite.
