Description

Cerous Carbonate is an inorganic salt of cerium, a rare earth element, with the chemical formula Ce2(CO3)3. This compound serves as a valuable precursor for synthesizing high-purity cerium oxide and other advanced cerium-based materials critical for modern industrial applications. It is essential for manufacturers and R&D facilities in sectors requiring specialized rare earth chemistry, such as catalysis, glass polishing, and phosphor production.

Application

• Catalyst Precursor: Used in the synthesis of cerium-based catalysts for automotive exhaust systems and various chemical processes.
• Glass & Ceramics Manufacturing: Acts as a polishing agent for precision optics and a decolorizing/coloring agent in specialty glass and ceramics.
• Phosphor Production: Serves as a starting material for producing cerium-doped phosphors used in lighting and display technologies.
• Chemical Synthesis: Employed as an intermediate in the preparation of other cerium salts and compounds for research and industrial use.
• Specialty Coatings: Utilized in formulations for coatings that require UV absorption or specific catalytic properties.

Quality Control

Our Cerous Carbonate is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets precise chemical and physical specifications. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your project requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material must be stored in a cool, dry place with minimal humidity fluctuation. Recommended storage temperature is 15-25°C. Keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture and carbon dioxide.
