Product Overview
Indium(I) iodide from eqipped is an ultra-high-purity (99.998% metals basis) reagent packaged under rigorous UltraDry™ conditions to eliminate moisture and oxygen contamination. This air-sensitive compound is critical for applications demanding exceptional purity, such as semiconductor fabrication, where trace impurities can compromise performance. The UltraDry™ packaging ensures long-term stability by preventing hydrolysis or oxidation during storage, making it ideal for laboratories requiring reproducible results in moisture-sensitive protocols. Unlike standard-grade indium halides, this product undergoes advanced purification to remove residual metallic contaminants, ensuring consistency in thin-film deposition, organometallic catalysis, and dopant applications. Its crystalline or powdered form dissolves readily in polar solvents, facilitating precise stoichiometric control in synthesis. Researchers working with perovskite solar cells, III-V compound semiconductors, or low-temperature synthesis will benefit from its tightly controlled impurity profile, which minimizes defect formation in final materials. The 1g and 5g pack sizes cater to both small-scale experiments and pilot production, while the UltraDry™ seal guarantees integrity until use.
FAQs
1. How does UltraDry™ packaging differ from standard airtight containers for indium(I) iodide?
The UltraDry™ system combines oxygen scavengers, desiccants, and hermetic sealing under inert gas (argon/nitrogen) to achieve <1 ppm moisture and <5 ppm oxygen levels, unlike standard containers that only provide a physical barrier. This prevents hydrolysis of the iodide to indium oxyiodides, which can alter reactivity.
2. Can this product be used directly for vapor-phase deposition without further purification?
Yes, the 99.998% metals basis purity and UltraDry™ handling make it suitable for direct use in chemical vapor deposition (CVD) or physical vapor deposition (PVD) systems. However, pre-degassing under vacuum is recommended to remove adsorbed gases from the crystal surface for ultra-thin film applications.
3. What solvents are compatible with indium(I) iodide for solution-phase reactions?
It dissolves in polar aprotic solvents like acetonitrile, DMF, and DMSO, as well as Lewis basic solvents such as pyridine or THF. Avoid protic solvents (e.g., alcohols, water) due to rapid hydrolysis. For organometallic synthesis, anhydrous conditions and glove-box handling are mandatory.
4. What is the typical shelf life when stored unopened in the original packaging?
When stored at 2–8°C in the unopened UltraDry™ container, the product retains its specified purity for 24 months. After opening, it should be used within 3 months or repackaged under inert gas to prevent degradation from ambient moisture.
5. Are there lower-purity alternatives available for less critical applications?
For applications where trace metal impurities are less concerning (e.g., preliminary screening), indium(I) iodide at 99.9% or 99.5% purity is available. However, these grades may contain higher levels of lead, tin, or zinc, which can affect electronic or optical properties in advanced materials.
