Quality Control

Our Cerous Carbonate is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets high-purity standards, with key parameters including assay (Ce2(CO3)3 content) and control of heavy metal impurities. A Certificate of Analysis (COA) detailing purity, physical characteristics, and trace element levels is provided with every shipment to guarantee batch-to-batch consistency for your applications.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material should be stored in a cool, dry place with minimal humidity fluctuation. For long-term storage, consider using a desiccator or inert atmosphere to prevent moisture uptake and potential caking.
