Green Silicon Carbide is produced basically in the same way of black silicon carbide except the different requirement of raw materials. It?s crystallization have higher purity and hardness. Green silicon carbide is suitable for processing hard alloy, metallic and non-metallic materials with hard and brittle feature such as copper, brass, aluminium, magnesium, jewel, optical glass, eramics, etc.Super mcicropowder of it is also a kind of ceramics material. 化学成分 Chemical Composition (%) 粒度Grit Size Sic F.C.
