We explored bismuth-based oxide ion conductors by materials informatics (MI) predictions and experimental validations. Employing the virtual screening for 13384 oxides listed in the inorganic crystal structure database (ICSD), we selected four bismuth oxide systems, namely, SrTa₂Bi₂O₉, SrNb₂Bi₂O₉, BaNb₂Bi₂O₉, and CaTa₂Bi₂O₉ as candidates. The oxides were then made by a conventional solid state method, and the physical and conductive properties were characterized.
