WhatCerium dioxide CAS 1306-38-3？

Cerium dioxide light yellow white cubic powder. Relative density is 7.132. Melting point 2600 ℃. Insoluble in water and not easily soluble in inorganic acids. Reducing agents (such as hydroxylamine reducing agents) need to be added to assist in dissolution. It is easy to penetrate visible light, but has good absorption of ultraviolet light, while also making the skin look more natural.

Application

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.
