Cesium carbonate Usage And Synthesis
Description Cesium carbonate is an inorganic compound. It is a white solid under normal temperature and pressure. It is easily soluble in water and quickly absorbs moisture when placed in the air. Cesium carbonate aqueous solution is strongly alkaline and can react with acid to produce corresponding cesium salt and water, and release carbon dioxide. Cesium carbonate is easy to transform, can be used as a precursor of other cesium salts, and is a widely used cesium salt.

UsesCesium carbonate can be used as a modified layer between the active layer of the solar cell and the Al electrode to improve the conversion efficiency of the device, generate Al-O-Cs compounds, reduce the series resistance of the battery, and improve the short-circuit current and photoelectric conversion efficiency of the solar cell, and Due to the compactness of the cesium carbonate layer itself, the stability of the device has also been significantly improved. The strong metallic n-type heavy doping effect of cesium in cesium carbonate, the Al/CsCO cathode modified with cesium carbonate nano-interface can greatly increase the injection of electrons, and significantly improve the performance of the inverted top-emitting structure OLED device. Cesium carbonate is also used as a catalyst for the synthesis of alkyl aryl ethers.
PreparationThe method of preparing cesium carbonate using cesium alum as a raw material :1. To recrystallize cesium alum, add cesium alum in deionized water and heat to dissolve, after dissolving, cool to crystallize and filter, and obtain refined cesium alum after filtering;2. Transformation, add refined cesium alum in deionized water and heat to dissolve, obtain refined cesium alum solution after dissolving, slowly drip lime milk into refined cesium alum solution, and obtain cesium sulfate net solution after solid-liquid separation;3. Causticizing, the barium hydroxide solution is added to the cesium sulfate clean liquid in 2 to 3 times, and the barium sulfate solid and the causticizing liquid are obtained by centrifugal separation;4. Carbonization, concentration and evaporation, pass CO into the causticizing solution for carbonization, carbonize until the pH of the carbonization solution is 7 to 10, stand still, concentrate the carbonization supernatant after standing, and obtain a concentrated solution after cooling;5. Once fine filtration and drying, the concentrated liquid is filtered with a polymer filter device, the filtered filtrate is concentrated and crystallized and dried at low temperature to obtain a low-temperature material;6. High temperature decomposition, after high temperature decomposition of low temperature material, high temperature material is obtained;7. Secondary fine filtration, the high temperature material is dissolved in deionized water, and then filtered with a polymer filter device, and the filtered liquid is obtained after filtration;8. The clean liquid is concentrated and dried, and the filtered clean liquid is concentrated and dried to obtain cesium carbonate.
Chemical PropertiesColourless crystals or white powder
UsesA promoter of O-alkylation of alcohols.
UsesCatalyst in ethylene oxide polymerization; in coating for spatter-free welding of steel in CO2; in oxide cathode.
UsesCesium carbonate (Cs2CO3) is used in the beer-brewing industry to make the “head” of beer foamier. It is also used in glassmaking and to enhance the taste of mineral water.
Safety ProfileModerately toxic by ingestion. Mutation data reported. When heated to decomposition it emits acrid smoke and fumes. See also CESIUM.
Purification MethodsCrystallise it from ethanol (10mL/g) by partial evaporation. [D.nges in Handbook of Preparative Inorganic Chemistry (Ed. Brauer) Academic Press Vol I p 988 1963.]
