Henan Superior Abrasives - High Quality Silicon Carbide and Silica Fume Supplier

  Green silicon carbide grit is a very hard abrasive material . The hardness of it only ranks after diamond and B4C, and it is harder than black silicon carbide . So it is suitable to grinding large range of hard material such as titanium alloy, marble, carbide alloy, optical glasses, ceramics, etc. Green Silicon Carbide is produced at high temperature in an electric resistance type furnace with quarts sand and petroleum coke. The SiC purity of green silicon carbide is up to 99%min. It is an artificial brittle SiC with high thermal conductivity and high strength which get no decrease in 1000 centigrade. Product feature Green silicon carbide SIC for lapping from Henan Superior Abrasive offers superior properties such as: * low density * low thermal expansion, oxidation resistance * excellent chemical resistance * high thermal shock resistance * high wear and hardness resistance * high strength, high temperature resistance * high temperature strength Specification ...

  Product Description Silicon Carbide Silicon carbide includes black silicon carbide and green silicon carbide , among which: black silicon carbide is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, which are smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, its mechanical strength is higher than corundum, and it is brittle and sharp. Green silicon carbide is made from petroleum coke and high-quality silica as the main raw material, adding salt as an additive, and smelted at high temperature in a resistance furnace. Its hardness is between corundum and diamond, and its mechanical strength is higher than that of corundum.
