Green silicon carbide powder has the following advantages:
1. High hardness and wear resistance
Green silicon carbide (Green SiC) is a very hard material, although not as hard as diamond and cubic boron nitride and other superhard materials, but it can be comparable to boron carbide. This high hardness enables it to effectively cut sapphire crystals during grinding, reducing wear and improving grinding efficiency.
