· Rb4I2O

Rb₄I₂O is a mixed-cation ionic ceramic compound containing rubidium, iodine, and oxygen. This material belongs to the family of halide-containing oxides and is primarily of research interest rather than established industrial production. The compound's potential applications lie in solid-state chemistry, particularly in ion-conducting ceramics and specialized optical or electrolyte materials where rubidium's ionic properties and halide incorporation could offer advantages in conductivity or thermal stability.
