· CsAsF4

CsAsF₄ is an inorganic ceramic compound composed of cesium, arsenic, and fluorine that belongs to the family of metal fluoroarsenates. This material is primarily of research and experimental interest rather than established industrial use, studied for its crystal structure, thermal properties, and potential applications in specialized optical or electronic ceramics where arsenic-containing fluorides show promise.
