FAQs
1. What is the difference between Premion and standard-grade iridium oxide?
The Premion grade undergoes additional purification steps to achieve 99.99% metals basis purity, with stricter controls on trace elemental impurities compared to standard grades. This results in higher consistency in electrochemical performance and catalytic activity.
2. Can this iridium oxide be used in high-temperature applications above 1000°C?
Yes, the material maintains structural integrity and chemical stability at temperatures exceeding 1000°C, though prolonged exposure may require inert atmosphere conditions to prevent oxidation state changes.
3. What solvents are compatible with this powder for dispersion?
It disperses effectively in polar solvents like deionized water, ethanol, and isopropanol, though ultrasonic agitation is recommended for uniform suspension. Avoid halogenated solvents that may react with the oxide surface.
4. How should this product be stored to maintain its purity?
Store in the original airtight container under inert gas (argon/nitrogen) at room temperature. Exposure to humid air may lead to surface hydration, while oxidative environments could alter the Ir4+/Ir3+ ratio over time.
5. Are there any known incompatibilities with common lab materials?
The oxide reacts with strong reducing agents like sodium borohydride and may catalyze decomposition of organic peroxides. Avoid contact with reactive metals (e.g., aluminum, zinc) to prevent exothermic reactions.
