Piezas de espejo de escaneo óptico retrorreflector cerámico de carburo de silicio
Carburo de silicio (Sic) ceramics have excellent characteristics such as strong oxidation resistance, alta dureza, high thermal stability, high temperature strength, small thermal expansion coefficient, alta conductividad térmica, thermal shock resistance and chemical corrosion resistance. Por lo tanto, it is widely used in petrochemical, metallurgical machinery, aeroespacial, microelectrónica, automóviles, steel and other fields, and gradually shows advantages that other special ceramics cannot match.

strongest technical ceramic materials and has exceptional thermal conductivity, chemical resistance and low thermal expansion.* Extremely high hardness
* Resistente al desgaste
* Resistente a la corrosión
* Lightweight – Low Density
* Alta conductividad térmica
* High Young’s modulus
* Low thermal expansion coefficient
* Chemically and thermally resistant
* Outstanding thermal shock resistance
* Refractive index greater than a diamond
