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 include manufacturing specialty glasses (Surface ion exchange with cesium
salts improves corrosion or breakage resistance 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. |
