High Purity 98.5% Silicon Carbide Powder for Polishing Green Silicon Carbide for Refractory Factory
High Purity 98.5% Silicon Carbide Powder for Polishing Green Silicon Carbide for Refractory Factory
Green silicon carbide is characterized by extreme hardness (Mohs 9.4/2600 Knoop) which only ranks after CBN and B4C.
The abrasives made of silicon carbide are suitable for working on cast iron,non-ferrous metal,rock, leather,rubber,etc.It is also broadly used as refractory material and metallurgical additive.
