[charcoal treasure said] silicon carbide


Silicon carbide (SiC) is a compound semiconductor material composed of carbon and silicon, which has the characteristics of high hardness, high melting point, high thermal conductivity, high temperature resistance, corrosion resistance and so on. Silicon carbide mainly includes hexagonal (a-SiC) and cubic (B-SiC) two kinds of crystal structure, carbon atoms and silicon atoms arranged in a tetrahedral configuration. As a typical representative of the third generation semiconductor materials, silicon carbide is one of the most mature and widely used wide band gap semiconductor materials in crystal production technology and device manufacturing, and has formed a global chain of materials, devices and applications.
