UV Protection Cerium Oxide Ceo2 99.999% Cerium Oxide Powder For Glass

Cerium Oxide (CeO₂): Oxidizer, Glass Decolorizer, Opacifier, Heat-Resistant Alloys, UV Protection

Cerium oxide is an inorganic compound with the chemical formula CeO₂, appearing as a light yellow or yellowish-brown powder. It has a density of 7.13 g/cm³ and a melting point of 2397°C. It is insoluble in water and alkalis, and slightly soluble in acid.

Under conditions of 2000°C temperature and 15MPa pressure, cerium oxide can be reduced by hydrogen to form cerium(III) oxide (Ce₂O₃). When the temperature is around 2000°C and the pressure is 5MPa, cerium oxide appears slightly yellow with a reddish tint or pinkish color.

Applications

1. Oxidizing agent. Catalyst for organic reactions. Used as a rare earth metal standard in steel analysis. For redox titration analysis.
2. Decolorizing agent for glass.
3. Opacifier for glass and enamel.
4. Heat-resistant alloys.
5. Used as an additive in the glass industry and as a grinding material for flat glass.
6. Also used in cosmetics for UV protection. Applications extend to eyeglass lenses, optical lenses, serving functions such as decolorization, clarification, and absorption of UV and electron beams in glass.

About Cerium Oxide
The primary production method for cerium oxide is the oxalate precipitation method. This process uses cerium chloride or cerium nitrate solution as the raw material, adjusts the pH to 2 with oxalic acid, and then adds ammonia water to precipitate cerium oxalate. After heating and aging, the precipitate is separated, washed, and dried at 110°C. It is then calcined at 900–1000°C to form cerium oxide.

Pure cerium dioxide (CeO₂) is a light yellow powder, while impure forms may appear beige or even pink to reddish-brown (due to traces of lanthanum, praseodymium, etc.). It is nearly insoluble in water and acid. Relative density: 7.3. Melting point: 1950°C, boiling point: 3500°C.
