· Rb2S3

Rb2S3 (rubidium sulfide) is an inorganic ceramic compound belonging to the sulfide ceramics family, characterized by ionic bonding between rubidium cations and sulfide anions. This material remains primarily in the research and development phase rather than established commercial production, with potential applications in solid-state ionic conductors, battery electrolytes, and optical materials where rubidium's alkali metal properties and sulfide's anionic framework could enable novel electrochemical or photonic functionality.
