Cesium fluoride (CsF) is an ionic ceramic compound composed of cesium and fluorine that forms a cubic crystal structure. It is primarily used in specialized optical and electrochemical applications, particularly as an electrolyte material in certain electrochemical cells and as a component in fluoride-based optical systems due to its transparency in the infrared region. CsF is notably more hygroscopic and soluble than other alkali halides, making it less common for general-purpose ceramic applications but valuable in research contexts where its specific ionic conductivity and optical properties are critical.
