Product Overview

Cerium(IV) oxide, also known as ceric oxide, is a high-purity (99.9% trace metal basis) inorganic compound widely recognized for its exceptional stability and reactivity in laboratory environments. This fine, white to pale yellow powder exhibits remarkable catalytic properties, making it indispensable in advanced chemical processes. Its unique electronic structure allows it to function as both an oxidizing agent and a reducing agent under different conditions, providing versatility in various experimental setups. The material demonstrates excellent thermal stability, maintaining its structural integrity even at elevated temperatures, which is crucial for high-temperature applications. Its fine particle size ensures uniform dispersion in solutions and mixtures, enhancing reaction efficiency. The trace metal basis purity level guarantees minimal impurities, preventing unwanted side reactions that could compromise experimental results. This grade of cerium oxide is particularly valued for its consistency in performance across multiple batches, ensuring reproducible results in sensitive applications. The compound’s high refractive index also makes it useful in optical applications where light manipulation is required.

FAQs

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

The typical particle size ranges between 1-5 microns, though this may vary slightly between batches. For precise particle size distribution, we recommend checking the certificate of analysis provided with your specific batch.

2. Is this Cerium(IV) oxide compatible with aqueous solutions?

While Cerium(IV) oxide has limited solubility in water, it can form colloidal suspensions. The powder disperses well in acidic solutions, particularly in mineral acids like nitric or sulfuric acid, where it forms soluble cerium(IV) salts.

3. What alternatives exist for similar applications?

For catalytic applications, zirconium dioxide or titanium dioxide might serve as alternatives, though they offer different reactivity profiles. For polishing applications, aluminum oxide or diamond powder could be considered, depending on the specific hardness requirements.

4. How should this material be stored for long-term stability?

Store in a tightly sealed container in a cool, dry place away from incompatible substances. While the material is stable under normal conditions, exposure to moisture over extended periods may lead to slight hydration of the surface.

5. What is the source of this Cerium(IV) oxide?

Our Cerium(IV) oxide is synthesized through controlled thermal decomposition of cerium salts, followed by purification processes to achieve the 99.9% trace metal basis purity. The cerium source material is derived from monazite and bastnäsite ores.
