Rb₂S₅ is an inorganic ceramic compound composed of rubidium and sulfur, belonging to the family of alkali metal polysulfides. This material is primarily of research and specialized interest rather than established industrial production, with potential applications in solid-state ionics, energy storage systems, and advanced ceramics where sulfide-based compositions offer unique electrochemical or thermal properties.
