Cerium oxide

Cerium(IV) oxide for industrial applications
Cerium oxide - also known as cerium dioxide or cerium(IV) oxide - is an oxide powder that is widely used in industry due to its unique oxygen storage capacity and high chemical stability. The material is suitable for catalysis processes, glass refinement, polishing applications and as an additive in high-temperature processes. PROJECTOR supplies cerium oxide in technical quality for industrial customers with precise specifications - from stock in Duisburg or as a customized special batch.
Typical applications of cerium oxide:
Cerium oxide is used across all sectors - in the glass industry, automotive technology, fine polishing and in energy and environmental technology. Cerium oxide is particularly in demand as a polishing agent for glass, lenses and precision optical components. It is also used as an oxygen buffer in solid oxide fuel cells (SOFC) or as a catalyst component for reducing pollutants in the exhaust tract.
Typical areas of application:
- Glass deacidification and decolorization (e.g. for flat glass and borosilicate glass)
- Polishing agent for display and optical glass
- Oxide component in three-way catalysts
- Component in high-temperature ceramics and sensors
- Oxygen storage in SOFC systems
Special features:
- Good chemical and thermal resistance
- Yellowish to white in color - depending on purity and grain size
- Reversible oxygen uptake/release (Ce⁴⁺/Ce³⁺ redox system)
- High polishing effect with low abrasiveness
Technical specifications:
- Chemical formula: Cerium(IV) oxide
- Chemical Abstracts Service (CAS-No.): 1306-38-3
- EC Index Number (EC No.): 215-150-4
