Black silicon carbide(C)
It is used to grind cast iron, non-ferrous metals rubber, leather,
plastic, wood, mineral rocks, etc. It can also be used to manufacture
high-class refractory products. |

Black
silicon carbide is suitalbe for grinding cast iron、non-ferrous
metal、leather、rubber、wood、rock,it
also be used as high grade refractory material.
