Product Overview
Lanthanum(III) iodide (LaI₃) in UltraDry™ grade delivers exceptional 99.9% rare earth oxide (REO) purity, ensuring minimal impurities for critical applications. This anhydrous compound is highly hygroscopic, requiring strict moisture-controlled handling to maintain its integrity. The UltraDry™ designation guarantees ultra-low water content (<10 ppm), making it ideal for environments where trace moisture could compromise results. Its crystalline structure exhibits high thermal stability and optical transparency in the UV-visible range, properties leveraged in advanced material science. The compound’s high atomic number (Z=57) contributes to its effectiveness in radiation detection applications. Packaged under inert argon atmosphere, this product arrives in sealed containers to prevent oxidation or hydrolysis during storage. Researchers benefit from its consistent stoichiometry and lack of hydrate formation, eliminating variability in experimental outcomes. Note that this material requires glove box handling due to its air and moisture sensitivity.
FAQs
1. What precautions are needed when handling Lanthanum(III) iodide?
Always use an argon-filled glove box or dry nitrogen environment. Avoid exposure to air or moisture, as it rapidly forms hydrates. Wear appropriate PPE including gloves and safety goggles.
2. Can this be used for scintillation detector fabrication?
Yes, the high purity and UltraDry™ grade make it suitable for scintillator crystal growth, though additional purification steps may be required depending on specific detector requirements.
3. How should this product be stored long-term?
Store unopened containers at room temperature in a desiccator under inert gas. Once opened, reseal immediately and use within 6 months for optimal performance.
4. What’s the difference between this and anhydrous Lanthanum chloride?
Lanthanum iodide offers higher density and better optical properties for scintillation applications, while chloride has higher solubility in polar solvents. Iodide is preferred for radiation detection.
5. Is this compatible with standard Schlenk line techniques?
Yes, but ensure all glassware is thoroughly dried (120°C overnight) and the system is purged with inert gas before transfer to prevent moisture contamination.
