Abstract
Oxide-ion conducting ceramic materials, which include
pure oxide-ion conductors and mixed oxide-ion and
electronic or hole conductors, have received considerable
attention because of their potential application for oxygen
separation membranes, oxygen sensors, and solid oxide fuel
cells (SOFCs) electrolytes and cathodes.1 Perovskite-type and
perovskite-related materials have been widely investigated as
oxide-ion conductors.2 For example, the K2NiF4-type compounds
are known to exhibit high oxide-ion conductivity.3
Because the oxide-ion conductivity is strongly dependent on
crystal structure, it is necessary to design and synthesize novel
materials belonging to a new structure family for further
innovative developments of the oxide-ion conductors. Herein,
we report a new perovskite-related structure family with
AA′BO4 composition, which exhibits oxide-ion conduction.
Here, A and A′ are relatively larger cations and B is a smaller cation. In this work we have succeeded in solving the crystal structure of NdBaInO4 and show oxide-ion conduction in NdBaInO4. © 2014, American Chemical Society.
