Product Description

Product Description

Cerium Oxide is a high-purity, fine powder ranging in color from white to pale yellow. As a vital rare earth compound, it possesses unique chemical, optical, and catalytic properties, making it indispensable in modern high-tech and traditional industries. We supply premium-grade Cerium Oxide with consistent quality, tailored specifications, and reliable global delivery.

Key Characteristics & Performance:
High Purity & Versatile Grades: Available in purities from standard industrial (99%) to ultra-high purity (99.99%+), including nano-sized powders (e.g., 10-50 nm).
Exceptional Catalytic Properties: Exhibits excellent oxygen storage capacity (OSC) and reversible redox cycling (Ce³⁺ ↔ Ce⁴⁺), making it a highly effective catalyst and promoter.
Polishing Abrasive: Renowned for its precise, non-scratching polishing action on glass, silicon, and other hard surfaces, offering superior surface finishes.
UV Absorption & Optical Clarity: Effectively blocks ultraviolet radiation while maintaining high transparency in the visible spectrum, ideal for optical coatings and glasses.
Thermal Stability: High melting point (~2400°C) and chemical inertness at elevated temperatures, suitable for refractory and high-temperature applications.
Electrical Properties: Acts as an electrolyte in intermediate-temperature solid oxide fuel cells (IT-SOFCs) due to its high ionic conductivity.
Environmental Compatibility: Plays a key role in automotive catalytic converters to reduce harmful emissions, contributing to cleaner technologies.

Application

Primary Industrial Applications:

Polishing & Precision Optics:

Glass Polishing: The standard abrasive for polishing precision optical lenses, LCD glass, display screens, and ophthalmic lenses.
Semiconductor: Critical in chemical-mechanical planarization (CMP) slurries for silicon wafers and microelectronic devices.

Catalysis & Environmental Protection:

Automotive Catalysts: A key component in three-way catalytic converters to CO and hydrocarbons (HC) and reduce nitrogen oxides (NOx).
Industrial Catalysis: Used as a catalyst or support in petroleum refining, exhaust gas treatment, and chemical synthesis (e.g., water-gas shift reaction).
Fuel Cells: Serves as an electrolyte or buffer layer in solid oxide fuel cells (SOFCs).

Glass & Ceramics:

Decolorizing & UV Blocking: Acts as a decolorizer by neutralizing iron impurities in glass and as a UV-absorbing additive in sunglasses and architectural glass.
Colorant: Imparts bright yellow colors in ceramics and glassware.
Protective Coatings: Used in coatings to provide glass with scratch resistance and anti-reflective properties.

Advanced Materials & Electronics:

Wear-Resistant Coatings: Enhances the hardness and lifespan of alloys and thermal barrier coatings.
Gas Sensors: Utilized in oxygen sensor materials due to its sensitivity to oxygen partial pressure changes.
Phosphors & Luminescent Materials: A component in certain phosphors for lighting and displays.

Biomedical & Other Applications:

Antioxidant: Nano-ceria is researched for its biomedical applications due to its mimetic antioxidant enzyme properties.
