Cerium Dioxide

Introduction to Cerium Dioxide

Other Names: Ceric dioxide, Cerium Dioxide, Ceric oxide, Cerium Oxide, CAS  1306-38-3

Cerium oxide is an inorganic substance that appears as a pale yellow or yellowish brown powder. Density 7.13 g/cm³, melting point 2397 ℃, insoluble in water and alkali, slightly soluble in acid. At a temperature of 2000°C and a pressure of 15 MPa, cerium oxide can be reduced by hydrogen to obtain cerium trioxide. When the temperature is free between 2000℃ and the pressure is free at 5 MPa, cerium oxide appears slightly yellow, slightly red, and pink. Its properties include polishing materials, catalysts, catalyst carriers (additives), ultraviolet absorbers, fuel cell electrolytes, automotive exhaust absorbers, electronic ceramics, etc.

Cerium Dioxide Quality Indicator

Cerium Dioxide Applications:

Oxidizing Agent

Catalysts for organic reactions. Steel analysis as a rare earth metal standard sample. Redox titration analysis. Colored glass. Glass enamel sunscreen. heat-resisting alloy.

Industrial Additives

The glass industry uses it as an additive, as a grinding material for glass plates, and as an anti-UV agent in cosmetics. It has been expanded to the grinding of eyeglass glass, optical lenses, and cathode ray tubes, playing a role in decolorization, clarification, and absorption of ultraviolet and electron rays in glass.
