Abstract:
1. A process for producing a perovskite oxide having a composition expressed by a compositional formula, where each of A, B, and C represents one or more metal elements, A represents one or more A-site elements, each of B and C represents one or more B-site elements, O represents oxygen atoms, and the one or more B-site elements represented by B have composition different from the one or more B-site elements represented by C; the one or more A-site elements include bismuth as a main component; and the composition of said perovskite oxide satisfies the conditions (1), (2), and (3), where TF(PX) is a tolerance factor of the perovskite oxide expressed by the compositional formula A(B, C)O 3 , TF(ABO 3 ) is a tolerance factor of an oxide expressed by a compositional formula ABO 3 , and TF(ACO 3 ) is a tolerance factor of an oxide expressed by a compositional formula ACO 3 .
