What is Cerium Oxide?
Cerium oxide (CeO₂) is the most widely used non-magnetic rare earth oxide in industrial manufacturing. With a high oxygen storage capacity and exceptional abrasive properties, it serves as a critical input across glass polishing, automotive catalysis, advanced coatings, and energy applications. Terratec Resources supplies cerium oxide sourced from vetted producers with consistent purity grades and fully traceable provenance.
Purity Grades & Specifications
We supply cerium oxide in the following standard grades:
99.0% CeO₂/TREO — Industrial grade. Suitable for glass polishing compounds, abrasive slurries, and general catalyst applications.
99.5% CeO₂/TREO — High purity. Used in optical glass manufacturing, automotive catalytic converters, and UV-resistant coating formulations.
99.9% CeO₂/TREO — Ultra-high purity. Required for solid oxide fuel cell components, precision optical applications, and advanced ceramics.
Custom grades and particle size specifications available on enquiry. Certificate of Analysis provided with every shipment confirming assay, particle size distribution, and trace element content.
Typical Applications
Cerium oxide is a critical input across a broad range of industrial processes:
Glass & Optical Polishing — CeO₂ is the industry-standard abrasive for flat glass, optical lenses, LCD panels, and precision optics. Its hardness and chemical reactivity deliver a superior surface finish versus alternative abrasives.
Automotive Catalysis — Used in three-way catalytic converters as an oxygen buffer, enabling more efficient combustion and reducing NOx, CO, and hydrocarbon emissions.
UV-Resistant Coatings — Incorporated into architectural glass and specialty coatings to absorb UV radiation and prevent photo-degradation.
Solid Oxide Fuel Cells (SOFC) — Acts as an electrolyte or electrode component in next-generation energy systems requiring high ionic conductivity.
Packaging, Logistics & Documentation
Cerium oxide is supplied in 25kg polylined woven bags, 1mt jumbo bags, or custom packaging on request. Minimum order quantities and lead times are confirmed at the enquiry stage depending on grade, volume, and delivery destination.
All shipments are available on FOB or CIF terms to any nominated port worldwide. Standard documentation package includes:
— Certificate of Analysis (CoA) — Safety Data Sheet (SDS) — Country of Origin Certificate — Export Compliance Documentation — End-Use Declaration (where required by destination country)
Additional documentation including third-party lab verification and customs declarations can be arranged on request.Emergency Leak Response
