Used as a source of cesium in specialty glass formulations, enhancing thermal stability and resistance to chemical corrosion. Employed in optical fibers and scintillation counters due to its ability to transmit UV and visible light. Acts as a catalyst support in certain chemical reactions, particularly in hydrogenation processes. Utilized in the synthesis of cesium-containing ceramics for electronic applications. Also applied in laboratory settings as a reagent for precipitation and ion-exchange procedures.
