Product Description
Attributes  --------------------------------------------------------------------------------------------------------------------   Formula: CsI  Hill system formula: Cs1I1  CAS registry number: [7789-17-5]  Formula weight: 259.81  Class: iodide  Colour: white  Appearance: crystalline solid  Melting point: 626°C; 621°C  Boiling point: 1280°C  Density: 4510 kg m-3 Application  -------------------------------------------------------------------------------------------------------------------- One way to make caesium iodide is to react the hydroxide with hydroiodic acid. The resulting salt can then be purified by recrystallization.While not a normal route of preparation because of the expense, caesium metal reacts vigorously with all the halogens to form caesium halides. So, it burns with iodine, I2, to form caesium(I) iodide, CsI.Description  --------------------------------------------------------------------------------------------------------------------Cesium iodide (cesium iodide) is the material that is used with the largest known IR transmission, and sometimes for components in a variety of spectrophotometers. An extremely soft material, cesium iodide is extremely difficult to polish, then the compensation for the area will be affected. Doped with thallium, CsI (Tl) is a useful scintillator, which emits at a wavelength that is a good match for silicon photodiodes. cesium iodide matrices are used in security imaging systems.
