Cerium(III) carbonate Ce2(CO3)3, 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.
Molar mass： 460.26 g/mol
Appearance： white solid
Melting point： 500 °C (932 °F; 773 K)
Solubility in water：negligible
Cerium(III) carbonate is used in the production of cerium(III) chloride, and in incandescent lamps.
