99% Alumina for Reflector

Want to keep this datasheet? Save it now in your required format


The material of the ceramic reflector is 99% Al₂O₃. Its green body is fired at a suitable temperature to retain the proper porosity and strength. The surface of the ceramic reflector is coated with a high reflectivity ceramic glaze, so compared with the gold-plated reflector, it has long service life and diffuse reflection.
