The density of 7.13g / cm3. Melting point is 2397 °C. It is insoluble in water and alkali, slightly soluble in acid. The temperature is free from 2000 ℃, at 5Mpa pressure, cerium oxide was slightly yellowish red, and pink, its performance is to do polishing materials, catalysts, catalyst carriers (additives), UV absorbers, fuel cell electrolytes, automobile exhaust absorbers, electronic ceramics.

Uses:
1 It can be used for oxidant, organic reaction catalyst, steel analysis for rare earth metal standard, redox titration analysis, decolored glass, glass enamel sunscreens, heat-resistant alloy.
2 Used as a glass industry additive for plate glass grinding material, can also be used in cosmetics play a role in anti-UV. It has been expanded to the glasses, optical lenses, CRT grinding, from decolorization, clarification, the absorption of ultraviolet glass and electronic lines and so on.

3 The rare earth elements are used for the decolorization of glass, they are mainly ceria and neodymia. Rare earth glass bleaching agent can replace the traditional use of bletilla striata, not only to improve efficiency, but also to avoid the pollution of white snakehead. Cerium oxide is used for glass bleaching with high temperature performance, low price and does not absorb visible light and so on.
4 The use of cerium oxide can instead of the traditional arsenic as a glass clarifier to remove air bubbles and trace elements, the effect is notable in the preparation of colorless glass bottles, the finished product crystal fluorescent is white, good transparency, glass strength and heat resistance increased. It also eliminates arsenic pollution of the environment and glass.
