Product DescriptionBlack silicon carbide is produced at high temperature in an electric resistancetype furnace with quarts sand and petroleum coke as its main raw meterials. Its hardness is between fused alumina and synthetic diamond. Mechanical intensity of it ia hig-her ghan fused alumina. It is britte and sharp and has electrial and heat xonduxtivity in some degree. The abrasives made of it aresuitable for working on cast iron, non-ferous metal, rock, leather, rubber, etc. It is also broadly used as refractory material and metallurgical additive.More Product FeaturesModel NO.: GB\FEPA\JIS\ISOStandard:GB\FEPA\JIS\ISOProductivity:Large Quantity
