Product Overview
Copper(I) iodide from eqipped is a Puratronic™ grade reagent with 99.998% purity (metals basis), engineered for applications demanding ultra-low trace metal contamination. This high-purity crystalline powder is synthesized under stringent conditions to eliminate impurities, ensuring consistency in semiconductor manufacturing, optical thin-film deposition, and advanced material research. The Puratronic™ designation guarantees a maximum of 2 ppm total metallic impurities, making it suitable for sensitive analytical techniques like ICP-MS or AAS where background interference must be minimized. Its stoichiometric precision and particle size distribution are optimized for uniform dispersion in solvent-based systems or vapor-phase processes. The compound’s stability under inert conditions and compatibility with organic solvents further enhance its versatility in specialized synthesis protocols. Unlike technical-grade alternatives, this product undergoes rigorous lot-to-lot testing for halogen, alkali, and transition metal contaminants, with certificates of analysis provided for each batch. The packaging in airtight, moisture-resistant containers preserves its purity during storage and handling, reducing the risk of oxidative degradation or hydration.
FAQs
1. What is the difference between Puratronic™ and standard-grade copper(I) iodide?
Puratronic™ grade ensures 99.998% purity with a maximum of 2 ppm total metallic impurities, while standard grades typically contain 98-99% purity with higher trace metal levels, making them unsuitable for semiconductor or optical applications.
2. Can this product be used for vapor deposition processes?
Yes, the ultra-low impurity profile and controlled particle size make it ideal for physical vapor deposition (PVD) or chemical vapor deposition (CVD) in thin-film applications, provided the system is maintained under inert conditions.
3. How should I store copper(I) iodide to maintain its purity?
Store in the original airtight container under nitrogen or argon at room temperature, away from light and moisture. Exposure to air or humidity can lead to oxidation or hydrolysis, compromising its purity.
4. Is this product compatible with organic solvents like acetone or ethanol?
It dissolves in polar organic solvents such as acetone, ethanol, or acetonitrile, but solubility varies with temperature. Always use anhydrous solvents to prevent reaction with residual water.
5. What alternatives exist for applications requiring lower purity?
For less demanding applications, technical-grade copper(I) iodide (98-99% purity) or ACS-grade (99%+) may suffice, though they contain higher levels of metallic and anionic impurities.
