Product Overview
Lanthanum(III) oxide (La₂O₃) from REacton™ delivers exceptional 99.999% purity (REO basis), making it a premium choice for applications where trace impurities can compromise results. This fine, white powder exhibits high thermal stability and excellent reactivity, ensuring consistent performance in demanding laboratory environments. The REacton™ grade undergoes rigorous purification processes to eliminate metallic and non-metallic contaminants, providing researchers with a reliable material for critical experiments. Its hygroscopic nature requires careful handling, but this property also contributes to its effectiveness in moisture-sensitive reactions. The powder’s uniform particle size distribution enhances solubility and dispersion in various solvents, facilitating precise formulation control. Whether used as a precursor for lanthanum-based compounds or as a standalone reagent, this high-purity oxide maintains its chemical integrity across a wide temperature range. The product comes in hermetically sealed packaging to preserve its purity during storage and transportation.
FAQs
1. What is the difference between 99.999% and 99.9% lanthanum oxide?
The 99.999% grade contains 10 times fewer impurities than 99.9% material, with trace metal contaminants reduced to parts-per-million levels, which is critical for applications like optical coatings or semiconductor manufacturing where even minor impurities can affect performance.
2. Can this lanthanum oxide be used for making lanthanum chloride?
Yes, this high-purity oxide serves as an excellent starting material for synthesizing lanthanum chloride through reaction with hydrochloric acid, producing a chloride salt with minimal metallic impurities carried over from the oxide precursor.
3. How should I store this product to maintain its purity?
Store in a desiccator or airtight container under inert gas atmosphere, as the material is highly hygroscopic and will absorb moisture from air, which can lead to formation of hydroxides and reduce its effectiveness in reactions.
4. What safety precautions should I take when handling this powder?
Wear appropriate PPE including gloves, safety goggles, and a dust mask, as the fine particles can irritate skin and respiratory system; perform all operations in a fume hood to avoid inhalation of airborne particles during weighing or transfer.
5. Is this product compatible with standard laboratory glassware?
The powder can be safely handled in borosilicate glass containers, though for long-term storage or reactions involving strong acids/bases, PTFE-lined containers are recommended to prevent potential leaching of silica from glass surfaces.
