التطبيق
Cerium dioxide is used as an additive in the glass industry and as a grinding material for glass plates. It has been expanded to grind eyeglass glass, optical lenses, and cathode ray tubes, and has functions such as decolorization, clarification, absorption of ultraviolet and electron rays in glass. Also used as an anti reflective agent for eyeglass lenses, cerium titanium yellow is made with cerium to give the glass a light yellow color. Used as an impregnating agent for piezoelectric ceramics in ceramic glazes and the electronics industry. It is also used to manufacture highly active catalysts, incandescent covers for gas lamps, and fluorescent screens for X-rays.
