    In the present work, we have discovered a new oxide-ion conductor SrYbInO4 with CaFe2O4-type structure. SrYbInO4 is the first example of CaFe2O4-type pure oxide-ion conductors where the oxide-ion conduction is dominant. It was found that the activation energy for the oxide-ion conduction of SrYbInO4 of (13) eV is lower than that of a mixed conductor CaFe2O4 of eV. Studies on dielectric behaviour of an oxygen ion conducting ceramic In oxygen ion conductors, the electrical conduction occurs predominantly due to mobility of oxide ions starting materials were mixed in dry and wet (methanol) conditions to achieve homogeneity.

Oxide-ion conducting ceramic materials have received considerable attention because of their potential applications in solid oxide fuel cells, oxygen separation membranes, and gas sensors. The type of membrane used for oxygen purification is a mixed oxygen ion and electron conducting perovskite, for example La Sr Fe CO O 3.
