silicon carbide (SiC)
Silicon carbide (SiC) is a wide-bandgap ceramic material with high breakdown voltage, high electric field strength, and large current density characteristics. In addition, it has high thermal conductivity and better hardness, heat resistance, oxidation resistance, corrosion resistance, and high thermal conductivity than general ceramic materials. Therefore, in recent years, silicon carbide has been widely used in structural components in mechanical engineering and sealing components in chemical engineering, and even in extreme environments such as strong acid, strong alkali, high wear, high temperature, and aerospace.
Main features:
● Excellent wear resistance.
● Excellent corrosion resistance.
● Excellent oxidation resistance.
● High thermal conductivity, good heat transfer effect.
