Cerium Oxide (CeO₂) is the most economically significant of all Rare Earth Oxides. Extremely stable, hard, off-white to pale yellow powder characteristic of RRe compound. Cerium is unique among the REEs for its ability to easily switch between the +3 (Ce₂O₃) & +4 (CeO₂) oxidation states. This redox capacity is the basis for its major applications in catalysis and polishing. We are leading & trusted Cerium Oxide suppliers in the United States and worldwide, offering high-purity Cerium Oxide that meets quality and safety standards, with reliable lead times and global supply capability.

Chemical Properties & Specifications
Vital component in Three-Way Catalytic Converters (TWC). Acts as an Oxygen Storage Capacity (OSC) agent, absorbing and releasing oxygen to maintain optimal stoichiometry for converting CO, NOx, and unburnt hydrocarbons
Powerful UV-absorber and de-colorizer in glass and as a stabilizer/pigment in ceramics and dental materials
Superior abrasive for polishing precision optics, flat panel displays (FPDs), automotive glass, and semiconductors due to its unique combination of mechanical abrasion and chemical activity
High-purity CeO₂ is used as an electrolyte material in Solid Oxide Fuel Cells SOFCs) due to its ionic conductivity. ®
