Cerium Carbonate - High-Purity Rare Earth Carbonate Precursor for Catalysis, Polishing & Ceramics

Cerium Carbonate , also known as Cerium(III) Carbonate, is a high-value and widely applied rare earth carbonate compound with the mainstream CAS number 54451-25-1 and EINECS number 208-655-6. With the molecular formula Ce₂(CO₃)₃·xH₂O, it is a hydrated crystalline rare earth salt featuring stable chemical properties, low water solubility, excellent thermal decomposition performance and ultra-low impurity characteristics. As a fundamental upstream precursor in the cerium-based rare earth industrial chain, Cerium Carbonate serves as the core raw material for manufacturing various high-purity cerium derivatives, standing out for its controllable particle morphology, high chemical activity and outstanding batch stability, and is widely used in global catalysis, optical polishing, advanced ceramics, new materials and environmental protection industries.

We supply high-quality Cerium Carbonate with multiple complete purity grades, including 99%, 99.9% (3N) and 99.99% (4N) customized specifications. Adopting precise solution purification, controlled precipitation, low-temperature crystallization and sealed drying processes, our products present uniform white crystalline powder appearance with ultra-low heavy metal, iron and non-rare earth trace impurities. The material features stable crystal structure, low agglomeration rate and excellent sintering activity. Insoluble in water and conventional organic solvents, it can be completely converted into high-purity cerium oxide and other cerium salt products after high-temperature calcination, fully meeting large-scale industrial production and high-standard scientific research application requirements.

Core Properties & Product Advantages

Cerium Carbonate possesses unique functional advantages that differentiate it from other cerium-based rare earth salts. Firstly, it has excellent controllable thermal decomposition performance, with stable pyrolysis process and no residual carbon impurities after calcination, which ensures high purity and uniform particle size of downstream cerium oxide products, becoming the preferred precursor for high-end rare earth oxide preparation. Secondly, it features ultra-low soluble impurities and stable room-temperature chemical properties, no deliquescence or deterioration during long-term storage and transportation, greatly improving production stability and material utilization rate.

In addition, Cerium Carbonate has moderate chemical activity and superior compound compatibility. It can be well matched with various ceramic raw materials, catalyst carriers and polymer additives, delivering excellent modification and synergistic effects. Compared with cerium chloride and cerium nitrate, it has lower hygroscopicity, better sintering performance and no harmful ion residue, effectively avoiding secondary pollution and performance attenuation of finished materials. Our products adopt strict multi-stage impurity removal technology, with consistent batch quality and stable physical and chemical indicators, fully compliant with international industrial and environmental protection standards.
