Cerium oxide is a compound of cerium, with the chemical formula CeO2. Cerium has a +4 oxidation state here, exhibiting strong oxidizing properties, and it is a white or pale yellow solid.

Insoluble in water. Cerium dioxide has a molar mass of 172.115 g/mol. Melting point: 2400°C, boiling point: 3500°C. Cerium dioxide can be obtained from cerium oxide by oxidation.

Manufactured by: 2 CeO2 + O2 → 4 CeO. Cerium dioxide generally does not react with common acids. Under high temperatures, cerium dioxide reacts with carbon monoxide

Oxidation-reduction reaction occurs: 4 CeO? + 2 CO → 2 Ce?O? + 2 CO?↑.

Cerium can also form a +3 valence oxide, cerium(III) oxide (Ce2O3), but cerium dioxide is a stable compound under room temperature and atmospheric pressure.
