Product Overview
Lanthanum(III) oxide (La₂O₃) at 99.9% purity (trace metal basis) is a high-performance rare earth oxide designed for demanding laboratory and industrial applications. This fine white powder exhibits exceptional chemical stability and reactivity, making it a critical component in catalysis, optical glass production, and advanced ceramic formulations. The ultra-low impurity profile ensures consistent results in sensitive processes, while its high surface area enhances efficiency in catalytic reactions. The material is synthesized under stringent conditions to maintain its 99.9% purity, with trace metal analysis confirming minimal contamination from other rare earth elements or transition metals. Its hygroscopic nature requires careful handling, but this property also contributes to its effectiveness in moisture-sensitive applications. The oxide’s unique electronic structure provides excellent dielectric properties, making it valuable in specialized electronic components. When stored in airtight containers, it maintains its purity and reactivity over extended periods, offering reliable performance for repeated experimental use.
FAQs
1. What is the particle size distribution of this lanthanum oxide powder?
The powder typically features a fine particle size distribution in the sub-micron to low micron range, though exact specifications may vary between production batches. For precise particle size data, refer to the certificate of analysis included with your shipment.
2. How does this compare with lanthanum oxide of lower purity grades?
The 99.9% trace metal basis grade offers significantly reduced levels of metallic impurities compared to standard 99% or 99.5% grades. This makes it particularly suitable for applications where trace contaminants could affect results, such as in high-precision catalysis or optical materials.
3. What precautions should be taken when handling this material?
As a fine powder, it requires handling in a well-ventilated area with appropriate respiratory protection. The material is mildly irritating to skin and eyes, so gloves and safety goggles are recommended. Always store in a desiccator or sealed container to prevent moisture absorption.
4. Can this be used as a precursor for lanthanum-containing compounds?
Yes, this high-purity oxide serves as an excellent precursor for synthesizing various lanthanum salts, complexes, and other compounds. Its high reactivity ensures complete conversion in most synthesis routes while maintaining the purity of the final product.
5. What is the typical shelf life when stored properly?
When stored in its original packaging under dry conditions, the material maintains its specified purity for at least 24 months from the date of manufacture. Always check the expiration date on the container for batch-specific information.
