Silicon Carbide

The Black SiC product of High Density, Great Crystalline Form Hexagonal is made by Quartz Grain and petroleum Coke. We use advanced technology which comes from abroad. This product has high compact density, big grain of crystallize and high purity. The hardness and toughness of black Sic are better than green SiC, when they have same content. This product is applicable of grind-material, high refractory material, engineering pottery and porcelain and so on. This product was get the honour of “New Product of Country Grade” by National Scientifically and Technologial Ministry,General Business Circles Bureau, Tax Bureau, Supervision Bureau of Quality and Technology and Ministry of Foreigh Trade in 1998.
