difference between the structures of silicon importers

The crystal structure of silicon carbide is divided into hexagonal or rhoohedral α-SiC and cubic β-SiC (called cubic silicon carbide). Since α-SiC constitutes many different variants due to the different stacking sequences of carbon and silicon atoms in its crystal structure, more than 70 kinds have been found. β-SiC is converted to α-SiC at 2100 ° C or higher.
