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

Cesium carbonate can be used as an active layer of solar cell and Al electrodes between the modified layer, improve the efficiency of conversion device, generating Al - O - Cs compound, reduce battery series resistance, increase the short circuit current and the photoelectric conversion efficiency of solar cell, and due to the density of cesium carbonate layer itself, the stability of the device Chemicalbook also improved significantly. Due to the n-type heavy doping effect of cesium in cesium carbonate, the Al/CsCO cathode modified by cesium carbonate nanoscale interface can greatly improve electron injection and the performance of invert top-emitting OLED devices. Cesium carbonate is also used as a catalyst for the synthesis of alkyl aryl ethers.

Cesium carbonate is generally used in the preparation of other cesium salt basic raw materials, but also used in the catalyst industry, special optical glass industry, oil catalytic additives, analytical reagents, ceramic industrial grade and pharmaceutical industry and other fields.
