Product Overview

Cerium(IV) oxide, also known as ceria, is a high-purity inorganic compound offered under the REacton™ brand with 99.9% rare earth oxide (REO) content. This fine powder exhibits exceptional thermal stability and acts as a strong oxidizing agent, making it indispensable in advanced material applications. Its high surface area and uniform particle size distribution ensure consistent performance in catalytic reactions, where it serves as a promoter or support material. The material’s unique electronic properties, including its ability to switch between Ce³⁺ and Ce⁴⁺ oxidation states, make it highly effective in redox processes. Additionally, its hardness and chemical inertness contribute to its use in precision polishing applications for optics and semiconductors. The REacton™ grade ensures minimal impurities, with strict control over trace metals and anions, guaranteeing reproducibility in sensitive applications. This product is packaged under inert conditions to prevent moisture absorption and oxidation, preserving its reactivity and shelf life. Whether used in bulk or small-scale experiments, this cerium oxide delivers reliable results with batch-to-batch consistency.

FAQs

1. What is the particle size range of this Cerium(IV) oxide powder?

The REacton™ grade Cerium(IV) oxide typically features a sub-micron particle size distribution, with an average range of 0.5–2 microns, optimized for high surface area applications.

2. Is this product compatible with aqueous solutions for wet chemistry applications?

While Cerium(IV) oxide is insoluble in water, it can be dispersed in acidic or alkaline solutions for specific reactions, though its primary use is in solid-state or heterogeneous systems.

3. Are there lower-purity alternatives available for cost-sensitive applications?

Lower-grade cerium oxide (e.g., 99.5% REO) is available but may contain higher levels of impurities like iron or silicon, which could affect performance in high-precision tasks.

4. How should this product be stored to maintain its reactivity?

Store in a tightly sealed container under dry, inert conditions (e.g., nitrogen or argon) to prevent hydration or carbonation, which can reduce its catalytic efficiency.
