RbSbF2

RbSbF₆ is an inorganic ceramic compound composed of rubidium, antimony, and fluorine—a halide-based material in the fluoroantimonate family. This is a research-phase compound investigated for specialized applications requiring high ionic conductivity and chemical stability in fluorine-rich environments, particularly as a potential solid electrolyte or ion conductor in electrochemical devices. While not yet established in mainstream industrial production, fluoroantimonate ceramics are notable for their ability to conduct fluoride ions at moderate temperatures, making them candidates for advanced battery chemistries and gas-sensing applications where conventional oxide ceramics fall short.
