Cerium oxide is a kind of white powder. It is insoluble in water and alkali, but it is sparing soluble in acid. People can get Dicerium trioxide by hydrogen reduction of cerium oxide under the condition of 2000℃ tempreture and 15Mpa pressure.
Cerium(IV) oxide, also known as ceric oxide, ceria, cerium oxide or cerium dioxide, is an oxide of the rare earth metal cerium. It is a pale yellow-white powder with the chemical formula CeO2.
Cerium(IV) oxide is formed by the calcination of cerium oxalate or cerium hydroxide.
Powdered ceria is slightly hygroscopic and will also absorb a small amount of carbon dioxide from the atmosphere.
Cerium also forms cerium(III) oxide, Ce2O3, but CeO2 is the most stable phase at room temperature and under atmospheric conditions.
