Product Overview
Indium(III) nitrate hydrate from the Puratronic™ series represents the gold standard for ultra-high-purity metal salts, engineered for applications demanding exceptional traceability and minimal impurities. This 99.999% (metals basis) grade material undergoes rigorous multi-stage purification to eliminate residual metallic contaminants, ensuring consistent performance in sensitive processes. The hydrated crystalline form provides excellent solubility in aqueous and polar organic solvents, making it ideal for homogeneous solution-based synthesis. Its low alkali metal content (<1 ppm) and controlled anion profile prevent unwanted side reactions in semiconductor fabrication and optical coating applications. The material's thermal stability allows for precise decomposition into indium oxide thin films during CVD or spray pyrolysis processes. Each batch is accompanied by comprehensive ICP-OES analysis certifying its ultra-high purity, with lot-specific certificates available upon request. The product is packaged under inert atmosphere to prevent moisture absorption and oxidation, preserving its pristine quality during storage and handling.
FAQs
1. What is the typical moisture content of this indium nitrate hydrate?
The hydrate form typically contains 5-7% bound water by weight, which is accounted for in the 99.999% metals basis specification.
2. Can this product be used directly for ALD precursor synthesis?
While suitable for many thin-film applications, additional purification steps may be required for atomic layer deposition precursors to meet volatility requirements.
3. What alternatives exist for lower-purity indium sources?
For less demanding applications, 99.99% or 99.9% indium nitrate grades are available, though they may contain higher levels of iron, copper, and lead impurities.
4. How should this material be stored to maintain purity?
Store in original sealed packaging at 15-25°C in a desiccated environment, protected from light and atmospheric moisture to prevent hydrolysis.
5. What analytical methods verify the 99.999% purity claim?
The purity is confirmed through inductively coupled plasma optical emission spectroscopy (ICP-OES) with detection limits at ppb levels for metallic impurities.
