Silicon carbide crystallizes in a close packed structure covalently bonded to each other. The atoms are arranged so that two primary coordination tetrahedral where four carbon and four silicon atoms are bonded to a central Si and C atoms are formed. These tetrahedra are linked together through their corners and stacked to form polar structures.
Silicon carbide has been recognized as an important structural ceramic material because of its unique coination of properties, such as excellent oxidation resistance, strength retention to high temperatures, high wear resistance, high thermal conductivity, and good thermal shock resistance.
Since it is epitaxially grown it possesses high quality crystal structure without grain boundaries while can be grown on an area as large as the SiC wafer (150 mm available on the SiC market presently).
