Cerium(III) carbonate Ce<sub>2</sub>(CO<sub>3</sub>)<sub>3</sub>, is the salt formed by cerium(III) cations and carbonate anions. Its pure form was not yet confirmed to exist in the nature, but Ce-bearing carbonates (mainly bastnäsite group) stand for an ore of cerium metal, along with monazite.
The molecular weight of the compound of cerium(III) carbonate is 460.26 g/mole.
Cerium(III) carbonate is also known as cerium tricarbonate, dicerium tricarbonate, cerium carbonate, cerous carbonate, and dicerium(3+) ion tricarbonate.
Cerium(III) carbonate is used in the production of cerium(III) chloride, and in incandescent lamps.
