Cesium Iodide, denoted by its CAS number 7789-17-5, is an inorganic salt with the chemical formula CsI. NINGBO INNO PHARMCHEM CO., LTD., a distinguished chemical manufacturer and supplier in China, offers this compound in its characteristic white powder form, highlighting its high purity, often exceeding 99%. Understanding the fundamental properties of Cesium Iodide is crucial for leveraging its diverse applications in advanced technologies and scientific research.

Key physical properties of CsI include its relatively high melting point of 626°C and boiling point of 1280°C. It is highly soluble in water and soluble in alcohol, and importantly, it is hygroscopic, meaning it readily absorbs moisture from the air. This property necessitates proper storage in tightly sealed containers to maintain its integrity. As a general chemical reagent, this characteristic is an important consideration for laboratory practices.

The applications of Cesium Iodide are widespread and technologically significant. It is famously used as a scintillator material in X-ray detectors, where it efficiently converts X-ray photons into visible light, enabling high-resolution imaging. This application is vital in medical diagnostics and industrial inspection. For those looking to purchase CsI for these advanced uses, quality is paramount.

In the realm of optics, CsI serves as an excellent material for beam splitters and transmission windows in infrared spectrophotometers, particularly Fourier Transform Infrared (FTIR) devices. Its optical transparency in the infrared spectrum is key to its functionality in these instruments. The study of scintillator material uses reveals the broad impact of CsI.

Furthermore, Cesium Iodide is employed in scintillation counters for radiation detection and can act as a 'getter' in vacuum tubes. The synthesis of pure CsI typically involves reactions like cesium carbonate with hydriodic acid. NINGBO INNO PHARMCHEM CO., LTD. ensures that its Cesium Iodide meets the high standards required for these demanding applications, making it a reliable source for researchers and industries worldwide. By understanding the detailed chemical properties, one can better appreciate the value of this compound.
