High purity green silicon carbide on sale, excellent green color, best choice for bonded abrasives, solar cell cutting, high grade metallurgical, grinding and lapping material.
Green silicon carbide is well noted as one of nice artificial material , also named emery grain or carborundum , which is produced by high-temperature smelting of electric furnaces such as quartz sand, petroleum coke , and wood chips ,require the addition of salt when producing. specific gravity of 3.20 ~ 3.25, microhardness of 2840 ~ 3320kg / mm2.
Main application: solar wafer,semiconductor wafer and quartz chip wire sawing and lapping, bonded and coated abrasive tools:stone polishing;processing metal and non-ferrous metal with low tensile strength ,such as:gray pig iron ,brass,aluminum ,stone,leather and rubber.
The production method of green silicon carbide micropowder is basically the same as that of black silicon carbide, but the requirements for raw materials are different. Green silicon carbide is made of petroleum coke and high-quality silica as the main raw material. It is added with salt as an additive and is smelted by high temperature furnace.The crystals which are smelted have high purity and hardness, and the hardness is between corundum and diamond. Mechanical strength Higher than corundum.
