Description:
Cerium Oxide (CeO₂) nanoparticles are high-purity, light yellow powders with exceptional optical, catalytic, and polishing properties. Known for their stability and high oxygen storage capacity, they are widely used in catalysis, solid oxide fuel cells, optics, and precision polishing applications.
With a specific surface area of 20–30 m²/g and a narrow particle size distribution (~100 nm), CeO₂ nanomaterials exhibit strong ultraviolet absorption (with a peak at ~400 nm, the highest among oxides), excellent oxidation resistance, and high-temperature stability. These properties make them ideal for use as buffer layers in superconductors, catalysts in automotive and chemical processes, and advanced polishing media for glass and semiconductor manufacturing.
Applications:
Catalysis: Automotive three-way catalysts, oxidation/reduction catalysts, catalyst supports.
Optics: Coatings for infrared filters, coloring agents for plastics, UV absorbents.
Energy systems: Electrolyte/electrode materials for solid oxide fuel cells, oxygen pumps, oxygen sensors.
Surface finishing: Precision polishing of optical lenses, glass, ceramics, semiconductors, and bearing balls.
Coatings: Heat-resistant alloys, oxidation-resistant layers.
Advanced materials: Sintering additives, buffer layers for superconductors.
