Silicon carbide ceramic retroreflector optic scan mirror parts
Silicon carbide (SiC) ceramics have excellent characteristics such as strong oxidation resistance, high hardness, high thermal stability, high temperature strength, small thermal expansion coefficient, high thermal conductivity, thermal shock resistance and chemical corrosion resistance. Therefore, it is widely used in petrochemical, metallurgical machinery, aerospace, microelectronics, automobiles, steel and other fields, and gradually shows advantages that other special ceramics cannot match.
