Product Overview
Erbium(III) iodide (ErI₃) from Eqipped’s UltraDry™ series delivers exceptional purity at 99.9% rare earth oxides (REO), ensuring minimal trace impurities for critical applications. This anhydrous, moisture-sensitive compound is meticulously packaged under inert conditions to prevent hydrolysis, preserving its high reactivity and optical clarity. The crystalline powder form offers uniform dispersion in organic solvents, making it suitable for advanced materials research, including dopant applications in semiconductor fabrication and specialty glass production. Its tightly controlled stoichiometry eliminates batch-to-batch variability, while the UltraDry™ processing guarantees low water content (600°C) and compatibility with glove-box handling further enhance its utility in air-sensitive workflows. Whether used as a precursor for erbium-doped fibers or in coordination chemistry, this grade ensures reproducible results with minimal purification steps required.
FAQs
1. What is the difference between UltraDry™ and standard erbium iodide grades?
UltraDry™ erbium(III) iodide undergoes rigorous drying processes to achieve <50 ppm moisture content, unlike standard grades that may contain absorbed water or hydrous forms, which can interfere with reactions.
2. Can this compound be used directly in solvent-based reactions without further drying?
Yes, the UltraDry™ grade is pre-dried and packaged under argon, eliminating the need for additional drying steps in most anhydrous solvent systems like THF or toluene.
3. What precautions are needed for long-term storage of erbium(III) iodide?
Store unopened containers in a desiccator under inert gas (argon/nitrogen) at room temperature. Avoid exposure to air or humidity, as it rapidly forms hydrates.
4. Is this product compatible with standard Schlenk line techniques?
The powder’s fine particle size and low moisture content make it ideal for Schlenk line transfers, though we recommend using a glove box for initial weighing to prevent oxidation.
5. Are there lower-purity alternatives available for less critical applications?
Eqipped offers 99.5% REO erbium iodide for general lab use, but the UltraDry™ 99.9% grade is recommended for optical or electronic applications where trace impurities impact performance.
