What is Cesium Carbonate used for?

Cesium Chloride is used in the preparation of electrically conducting glasses and screens of cathode ray tubes. Conjuncting with rare gases, CsCl is used in excimer lamps and excimer lasers. Other application such as activation of electrodes in welding, manufacture of mineral water, beer and drilling muds, and high-temperature solders. High-quality CsCl has been used for cuvettes, prisms and windows in optical spectrometers. It can also be useful in electrophyisiology experiments in neuroscience.
