Product Overview
Cesium iodide (CsI) in UltraDry™ grade delivers exceptional purity at 99.998% (metals basis), making it a critical material for applications where trace impurities can compromise performance. This high-purity compound is processed under stringent conditions to eliminate moisture and volatile contaminants, ensuring long-term stability and reliability in sensitive environments. The crystalline powder form provides excellent solubility in polar solvents while maintaining structural integrity under varying thermal conditions. Its low hygroscopicity compared to standard grades reduces handling challenges, making it suitable for environments requiring precise stoichiometric control. The material’s optical transparency in the infrared spectrum and high scintillation efficiency further expand its utility in photonics and radiation detection systems. Each batch undergoes rigorous spectroscopic and elemental analysis to confirm compliance with ultra-high purity standards, providing researchers with consistent, reproducible results.
FAQs
1. What is the difference between UltraDry™ and standard-grade cesium iodide?
The UltraDry™ grade undergoes additional purification steps to reduce moisture content below 50 ppm and eliminate trace metal impurities, unlike standard grades which may contain higher levels of contaminants and absorbed water.
2. Can this product be used in vacuum-sealed applications?
Yes, the UltraDry™ processing minimizes outgassing and volatile residues, making it compatible with high-vacuum environments typically used in semiconductor fabrication or mass spectrometry.
3. What is the typical shelf life when stored unopened?
When stored in the original sealed container under inert gas, the product maintains its specified purity for at least 24 months from the date of manufacture.
4. Are there any known incompatibilities with common lab solvents?
Cesium iodide is highly soluble in water and alcohols but reacts violently with strong acids like sulfuric or nitric acid, releasing toxic hydrogen iodide gas.
5. How does the particle size distribution affect performance in scintillation applications?
The crystalline powder is milled to a consistent 10-50 micron range, optimizing light output uniformity in scintillation detectors while minimizing scattering losses in optical applications.
