Introduction to ceramic reflector 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. Production Process Preparation of the green body Preparation of glaze slurry: raw material weighing – grinding – screening Glazing: glazing by spraying Glaze burning: the glazed product is burning at a high temperature Inspection: Appearance inspection, dimensional measurement, and reflectance measurement Packaging Prime Features Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity 97% reflectance efficiency at 600-1000nm Reflectance efficiency exceeds 95% across the wavelength range 400-1200nm (see curve) Controlled porosity Good thermal conductivity High electrical resistivity ...

They are also extensively used as reflectors in housings for high intensity lamps. Ceramic reflectors can be glazed both inside the cavity and the out surface using a highly reflective glaze that seals the ceramic against ingress of cooling fluids that may alter the refractive index, introduce impurities and reduce reflectance and efficiencies. Glaze can also act as filters and our yellow glazed reflectors have been used successfully in certain applications. The visible yellow colour is complementary to the spectral colours violet and indigo and effectively absorbs these wavelengths up to around 450 nm.
