· JVASP-104608· RbNa2Bi

RbNa2Bi is an intermetallic ceramic compound containing rubidium, sodium, and bismuth, belonging to the family of alkali metal bismuthides. This is a research-phase material rather than a widely commercialized industrial ceramic; compounds in this family are investigated for potential applications in thermoelectric devices, solid-state electrolytes, and photonic materials where the layered crystal structure and electronic properties of bismuth-based phases offer design advantages.
