Rare-earth carbonates cover cerium(III) carbonate (Ce2(CO3)3) and lanthanum carbonate (La2(CO3)3). Important precursors for rare-earth-oxide manufacturing, they are widely used within rare-earth separation-smelting, catalyst supports, special ceramics and polishing materials. Loss-on-ignition, particle-size distribution, chloride-content and elemental stoichiometry of carbonates directly govern calcination-process efficiency and final-oxide quality. Multiple grades from industrial- to high-purity are offered with custom-manufacturing available for targeted particle-size, morphology and impurity-level requirements. Strict elemental-assay and impurity-monitoring per batch are accompanied by complete test reports, enabling procurement managers to rapidly match specifications to downstream-process requirements and complete qualification.

Lanthanum Carbonate
Lanthanum Carbonate is a salt formed by lanthanum(III) cations and carbonate anions with the chemical formula La2(CO3)3. Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides.

Cerium(III) Carbonate
Cerium(III) Carbonate Ce2(CO3)3, is the salt formed by cerium(III) cations and carbonate anions. It is a water insoluble Cerium source that can easily be converted to other Cerium compounds, such as the oxide by heating (calcin0ation).Carbonate compounds also give off carbon dioxide when treated with dilute acids.
