| Applications | Uses: Used in x-ray screens and radiographic contrast medium, [Merck Index], In x-ray fluorescent screens, as radiographic contrast medium, in manuf of cesium., There are currently 160 gamma-irradiation facilities and over 600 electron-beam facilities in operation throughout the world. The most widespread uses of these facilities are the sterilization of medical and pharmaceutical products, the preservation of foodstuffs, polymer synthesis and modification, and the eradication of insect infestation For gamma facilities the source would typically be 60Co in the petabequerel range, some 137Cs sources are also used., Both x-ray equipment and sealed sources are used in industrial radiography. The most common sealed sources are 192Ir..., 60Co..., and 137Cs (activity between 0.3 and 80 GBq)., Methods of Manufacturing: Alkaline decomposition is carried out by roasting the pollucite ore with either a calcium carbonate-calcium chloride mix at 800-900 °C or with a sodium carbonate-sodium chloride mix at 600-800 °C followed by a water leach of the roasted mass. The resultant cesium chloride solution is separated from the gangue by filtration., Acid digestion of pollucite is the preferred commercial process for producing pure cesium. Hydrofluoric, hydrobromic, and sulfuric acid may be employed in this method. Hydrofluoric and hydrobromic acid digestion yield the greatest cesium recovery, but the inherent difficulties of safely handling these acids limit their use. Digestion with hydrochloric acid takes place at elevated temperatures and produces a solution of mixed cesium chlorides, aluminum, and other alkali metals separated from the siliceous residue by filtration. The impure cesium chloride can be purified as cesium chloride double salts that are then recrystallized. The purified double salts are decomposed to cesium chloride by hydrolysis or precipitated with hydrogen sulfide., Sulfuric acid digestion is performed at 110 °C with a 35-40% solution of sulfuric acid, followed by a hot water wash and vacuum filtration. Cesium alum is crystallized from the leach filtrate by stage cooling to 50 °C and then 20 °C, and roasted in the presence of 4% carbon. The residue is leached to produce cesium sulfate solution, which can be converted to cesium chloride., General Manufacturing Information: Cesium chloride (CsCl): ACTIVE, Not produced in the USA, although there is no information regarding the countries shipping cesium compounds (e.g., cesium chloride) to the USA, it is believed that Canada is the major source of cesium compounds (e.g., cesium chloride). |
