Ceramic Cavity for Alma Harmony and Harmony XL

Product Description

The Ceramic Cavity green body is made of 99% Al2O3, and the green body is fired at an appropriate temperature to retain proper porosity and proper green strength. The surface of the reflector is fully coated with high-reflectivity ceramic glaze. Compared with the gold-plated reflector, the biggest advantage lies in its extremely long service life and diffuse reflection.
