Product Overview
Erbium(III) chloride, UltraDry™, with 99.9% rare earth oxide (REO) purity, is a high-grade anhydrous compound designed for demanding laboratory applications. This moisture-sensitive material is processed under stringent conditions to eliminate residual water, ensuring maximum reactivity and consistency in specialized synthesis. The UltraDry™ designation guarantees minimal hydrate formation, making it particularly suitable for applications where trace moisture could compromise results. Its fine, free-flowing powder form allows for precise weighing and uniform dispersion in reaction mixtures. The 99.9% REO specification confirms exceptional purity, with tightly controlled impurities to prevent interference in sensitive procedures. This grade of erbium chloride serves as a reliable precursor for advanced material development, offering consistent performance in optical, electronic, and catalytic applications. The product is packaged under inert atmosphere to maintain its anhydrous state during storage and handling. Researchers benefit from its high solubility in polar solvents and compatibility with standard Schlenk techniques for air-sensitive chemistry.
FAQs
1. What precautions should be taken when handling UltraDry erbium(III) chloride?
Always work in a dry, inert atmosphere like a glovebox or under nitrogen purge. The material is extremely hygroscopic and should never be exposed to ambient air. Use oven-dried glassware and moisture-free solvents to prevent hydrolysis. Standard laboratory PPE including gloves, goggles, and lab coat are essential due to its irritant properties.
2. How does the UltraDry grade differ from regular erbium chloride?
The UltraDry grade undergoes additional drying processes to achieve lower moisture content (typically <50 ppm) compared to standard hydrated forms. This results in higher reactivity, better solubility in non-aqueous systems, and eliminates the need for in-situ dehydration. The anhydrous nature also prevents weight variations from absorbed moisture during storage.
3. What solvents are compatible with this erbium chloride for preparation?
The compound exhibits excellent solubility in polar aprotic solvents like THF, acetonitrile, and DMSO. It also dissolves well in alcohols, though these may partially coordinate with the erbium center. For non-polar solvents, addition of coordinating ligands or crown ethers may be required to achieve dissolution.
4. Can this product be used for thin film deposition techniques?
Yes, the high purity and anhydrous nature make it suitable for physical vapor deposition methods. It serves as an excellent precursor for erbium-doped films in optical applications. The low impurity profile minimizes defect formation in deposited layers, while the consistent stoichiometry ensures reproducible film properties.
5. What storage conditions are recommended to maintain product quality?
Store unopened containers in a desiccator under inert gas at room temperature. Once opened, reseal immediately with parafilm and store under nitrogen. Avoid temperature fluctuations and never store near water sources or in high-humidity environments. Properly stored material maintains specifications for at least 12 months from date of manufacture.
