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.
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.
