Product Overview
Lanthanum(III) oxide (La₂O₃), offered in REacton™ grade with 99.9% purity (REO), is a high-performance rare earth oxide widely used in specialized applications requiring exceptional chemical stability and optical clarity. This fine, white powder exhibits low hygroscopicity, making it suitable for long-term storage without significant degradation. Its high refractive index and thermal stability render it indispensable in optical coatings, where it enhances light transmission and durability. In catalytic systems, lanthanum oxide acts as a promoter, improving reaction efficiency and selectivity. The material’s compatibility with glass and ceramic matrices allows for precise tuning of mechanical and thermal properties, making it a preferred choice in advanced material formulations. The REacton™ grade ensures minimal impurities, guaranteeing consistent performance in sensitive applications. Whether used as a standalone reagent or as a dopant, this lanthanum oxide variant delivers reliability in demanding laboratory and industrial environments.
FAQs
1. What is the particle size range of this lanthanum(III) oxide powder?
The typical particle size distribution falls within the sub-micron to low-micron range, though exact specifications can vary based on synthesis methods. For precise requirements, further characterization may be recommended.
2. Is this product compatible with aqueous solutions for synthesis?
While lanthanum oxide is sparingly soluble in water, it reacts with acids to form soluble lanthanum salts. Direct dissolution in neutral or alkaline aqueous media is limited without chemical modification.
3. Are there lower-purity alternatives available for cost-sensitive applications?
Lower-grade lanthanum oxide (e.g., 99.5% or 99.0% REO) is commonly available and may suffice for applications where trace impurities are less critical, such as certain ceramic or glass formulations.
4. How should this product be stored to prevent moisture absorption?
Store in a tightly sealed container under inert gas (e.g., nitrogen or argon) in a cool, dry environment. Desiccants can be added to the storage container for extended shelf life.
5. Does this lanthanum oxide contain any dopants or stabilizers?
This REacton™ grade product is supplied as pure lanthanum(III) oxide without intentional additives. Trace impurities, if present, are quantified within the 99.9% (REO) specification.
