Product Overview
Lanthanum(III) carbonate hydrate, REacton™ grade with 99.99% rare earth oxide (REO) purity, is a high-performance chemical compound designed for demanding laboratory and industrial applications. This hydrated form ensures stability and controlled reactivity, making it suitable for precision chemical synthesis where trace impurities can compromise results. The REacton™ designation guarantees consistent batch-to-batch quality, with rigorous testing for heavy metals and anionic contaminants. Its fine particle size distribution enhances solubility in acidic media, facilitating uniform reaction kinetics. The hydrate form provides a convenient moisture content that can be thermally removed if anhydrous conditions are required. This product is particularly valued in catalysis applications where lanthanum’s unique coordination chemistry enables selective transformations. The high REO purity minimizes interference from other rare earth elements, ensuring reproducible experimental outcomes. Packaged under inert conditions to prevent atmospheric contamination, this lanthanum carbonate maintains its specified purity throughout its shelf life when stored properly.
FAQs
1. What is the exact chemical formula of this lanthanum carbonate hydrate?
The product corresponds to La2(CO3)3·xH2O where x represents the variable water content in the hydrate form, typically ranging between 2-8 molecules depending on preparation conditions.
2. How does the REacton™ grade differ from standard laboratory grades?
REacton™ grade signifies ultra-high purity with 99.99% REO content, compared to standard grades that may contain 99-99.9% purity, along with stricter controls on trace metal impurities and particle size distribution.
3. What solvents is this lanthanum carbonate soluble in?
The compound is insoluble in water and organic solvents but dissolves readily in mineral acids like hydrochloric, nitric, or sulfuric acid, forming corresponding lanthanum salts.
4. What precautions should be taken when handling this chemical?
While generally stable, the powder should be handled in a fume hood to avoid inhalation, and standard PPE including gloves and goggles should be worn due to potential irritation from fine particles.
5. Can this product be used for preparing lanthanum oxide?
Yes, thermal decomposition at temperatures above 800°C will convert the carbonate to lanthanum oxide (La2O3) with high purity retention, though the exact conditions should be optimized for your specific requirements.
