Black Silicon Carbide Abrasive Grain F100 (Engineering Ceramic) Chemical Composition: SiC: 98.1% min FC: 0.10%max Fe2O3: 0.25%max Advantages: Black silicon carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke as its main raw materials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it is higher than fused alumina. It is brittle and sharp and has electrical and heat conductivity in some degree. The abrasives made of it 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. 1. Large melting furnace, longer melting time, lead to more crystallization, bigger crystals, higher purity and less impurities. 2. Good hardness, longer life.3. Chemical washed and water washed, good cleanness.4. Special treated products get higher purity, better toughness, and better grinding effect.Your satisfaction ,our pursuit.Best wishes from Zhengzhou Xinhua Charging Technology Co.,Ltd .
