Abstract:
1. A process for producing a piezoelectric oxide having a composition expressed by a compositional formula: where each of A, B, C, D, E, and F represents one or more metal elements, A, B, and C represent Pb, D, E, and F represent Ti, Zr, and M, respectively, M is at least one metal element selected from the group consisting of Sn, Nb, Ta, Mo, W, Ir, Os, Pd, Pt, Re, Mn, Co, Ni, V, and Fe, and O represents the oxygen atom, wherein a ratio of each of a total molar amount of A, B and C and a total molar amount of D, E and F to a molar amount of oxygen atoms may deviate from 1:3 within a range in which the composition expressed by the compositional formula (A, B, C)(D, F, F)O wherein the composition of said perovskite oxide satisfies conditions (1), (2), (3), and (4): where TF(P) is a tolerance factor of the piezoelectric oxide expressed by the compositional formula (A, B, C)(D, E, F)O 3 , TF(ADO 3 ) is a tolerance factor of a compound expressed by a compositional formula ADO 3 , TF(BEO 3 ) is a tolerance factor of a compound expressed by a compositional formula BEO 3 , and TF(CFO 3 ) is a tolerance factor of a compound expressed by a compositional formula CFO 3 .
