RbBa2P5O15

RbBa2P5O15 is a rare-earth-free phosphate ceramic compound containing rubidium, barium, and phosphorus oxides, belonging to the family of polyphosphate ceramics. This material is primarily investigated in research contexts for optical and electrolytic applications, particularly as a potential solid-state electrolyte or optical host material, with interest driven by its crystal structure and ionic conductivity characteristics. The compound represents an alternative to more common phosphate ceramics in specialized functional applications where conventional oxides or sulfides may be less suitable.
