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.
Currently, most research about oxide-ion conducting ceramics is limited to materials with specific structure-types, such as fluorites, perovskites, K2NiF4, mellilites, and apatites. However, it is necessary to investigate new structure-type ceramics for the further development of oxide-ion conductors.
Recently, a research group led by Masatomo Yashima and Kotaro Fujii of Tokyo Institute of Technology discovered the new crystal structure family of oxide-ion conductors of NdBaInO4 using a concept of structure design based on ionic size.
