| Cesium bromide Usage And Synthesis |
| Chemical Properties | Cesium bromide is a colourless crystals. It has been used in protein crystallization for anamolous scattering. |
| Uses | In x-ray fluorescent screens, spectrometer prisms, absorption-cell windows. |
| Uses | Cesium bromide (CsBr) crystals are used in scintillation counters to detect radiation. The compound is also used to coat the inside of fluorescent screens. |
| Uses | Cesium bromide is used as reagent, intermediate in pharmaceuticals. |
| Preparation | Caesium bromide can be prepared via following reactions: Neutralization: CsOH (aq) + HBr (aq) → CsBr (aq) + H2O (l) Cs2(CO3) (aq) + 2 HBr (aq) → 2 CsBr (aq) + H2O (l) + CO2 (g) Direct synthesis: 2 Cs (s) + Br2 (g) → 2 CsBr (s) The direct synthesis is a vigorous reaction of caesium with other halogens. Due to its high cost, it is not used for preparation. |
| Safety Profile | Moderately toxic by intraperitoneal route. See also CESIUM and BROMIDES. When heated to decomposition it emits toxic fumes of Br-. |
| Purification Methods | It is very soluble in H2O, soluble in EtOH but insoluble in Me2CO. Dissolve it in the minimum volume of H2O, filter and precipitate it by adding Me2CO. Filter off the solid and dry it at 100o. Also recrystallise it from water (0.8mL/g) by partial evaporation in a desiccator. |
