What is the material structure of green silicon carbide?
The crystal structure is divided into hexagonal or rhombohedral α-SiC and cubic β-SiC. Green silicon carbide is a transparent crystal. Industrial green silicon carbide varies directly with its purity due to the type and content of impurities.
α-SiC forms many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, and more than 70 kinds have been discovered. β-SiC is transformed into α-SiC above 2100℃. The industrial production method of green silicon carbide is made by high-quality quartz sand and petroleum coke in a resistance furnace. The refined green silicon carbide blocks are crushed, washed with acid and alkali, magnetic separation, sieving or water selection to produce products of various particle sizes.
The material structure of green silicon carbide can help future production and application. When using it, pay attention to other chemical substances. Green silicon carbide is a new type of material and a good raw material for making ceramics.
