APPLICATIONS

Cesium salts are used as mediums of density gradient centrifugation for DNA recovery and purification (high purity of cesium chloride, cesium sulfate, cesium trifluoroacetate) and as metal oxide catalyst enhancer for heterogeneous processes due to their ability to lower down high oxidation states of transition metal oxo anions. Some salts ( cesium bromide, iodide and fluoride) are used in scintillation counters and infrared spectroscopies as they absorb x-rays, gamma and particle radiation, and emit visible light. Industrial application of cesium salts includue manufacturing specialty glasses (Surface ion exchange with cesium salts improves corrosion or breakage resistances of glasses ) and in photoelectric cells, in optical instruments, for photosensitive deposit on cathodes and in filaments of electron tubes to increase sensitivity (cesium chlorite, carbonate, sulfate, nitrate, perchlorate). Cesium chloride is used in titanium dioxide manufacturing. They are used as components for propellants and drilling grouts. Cesium sulfate and fluoride are used for brewing and in mineral waters. Cesium Hydroxide is used as electrolyte in alkaline batteries at subzero temperatures, color photography and as a catalyst in organic synthesis.
