| Cesium iodide Usage And Synthesis |
| Description | Cesium iodide is a soft material and extremely hygroscopic. Cesium iodide scintillators have been used extensively for indirect x-ray imaging detectors, such as for CT examinations. Cesium iodide is also used to construct electromagnetic shower detector for the CLEO II experiment, which investigates electron-positron annihilation at center-of-mass energies near 10 GeV. Cesium iodide is useful for beam splitters for Far IR spectrophotometers and IR transmission windows. |

| Chemical Properties | white crystalline powder |
| Uses | Prisms for infrared spectroscopy; in x-ray fluorescent screens, scintillation counters. |
| Uses | Cesium iodide (CsI) is a kind of ionic compound that has been widely used as scintillators in many areas such as X-ray image intensifier tubes, photocathodes, and display devices. Cesium iodide is used in scintillation counters(Geiger counters) to measure levels of external radiation. It is also useful as a "getter" to remove air molecules remaining in vacuum tubes. Cesium Iodide is a material with high γ-ray stopping power due to its relative high density and atomic number. For scintillation counting, it is used either in its un-doped form or doped with sodium or thallium. CsI is resistant to thermal and mechanical shock. The physical characteristics of CsI are independent of the activator used. Compared to NaI(Tl), it is relatively soft and plastic, and does not cleave. Because it has no cleavage plane, it is quite rugged-which makes it well-suited for well logging, space research or other applications where severe shock conditions are encountered. |
| Uses | Cesium iodide is used in FT-IR (Fourier Transform Infrared Spectrometers) as a beamsplitter. Cesium Iodide exhibits high gamma-ray stopping power. Useful as input phosphor in fluoroscopy equipment, and efficient photocathode for extreme ultraviolet wavelengths. Fast and dense scintillating material - useful in electromagnetic calorimetry in particle physics. |
| General Description | Cesium iodide is a simple ionic salt. It has the capacity to undergo second order transformation from cubic B2 structure to body-centered tetragonal structure at low pressures. It is mostly used as input screens of X-ray image intensifiers. |
| Flammability and Explosibility | Non flammable |
| Safety Profile | Moderately toxic by ingestion and intraperitoneal routes. See also CESIUM and IODIDES. When heated to decomposition, it emits toxic fumes of I-. |
| Purification Methods | Crystallise it from warm water (1mL/g) by cooling to -5o. |
