Cesium carbonate is a kind of inorganic compound, white solid at room temperature and pressure, easily soluble in water, and the aqueous solution is strongly alkaline. It has a wide range of applications in industry and scientific research. In glass manufacturing, cesium carbonate can be used as an additive to improve the refractive index and electrical conductivity of glass. In addition, cesium carbonate is often used as an electrolyte material, a dielectric for capacitors, and a material for optoelectronic devices. In organic synthesis, cesium carbonate can be used as a catalyst carrier and participate in a variety of chemical reactions. In addition, cesium carbonate is also used in the field of medicine, such as as a carrier of radioactive isotopes for radiation therapy and radioactive tracers. The storage and transportation of cesium carbonate should be kept dry and away from combustible materials.
