Abstract

A (0.93 − x)Pb(Fe1/2Nb1/2)O3–0.07Pb(In1/2Nb1/2)O3xPbTiO3 (0.06 ≤ x ≤ 0.11) ternary system was synthesized using a B-site precursor solid-state reaction method. The maximum piezoelectric coefficient d33 = 673 pC N−1 was achieved at the morphotropic phase boundary (MPB) composition x = 0.09 and its Curie temperature was 141 °C. In situ high energy synchrotron X-ray diffraction (SXRD) results demonstrate that tetragonal and monoclinic phases coexist at the MPB composition. It is interesting to observe that the stable single monoclinic phase induced by the electric field exhibits the characteristics of flexible lattice parameters in response to the electric field. The large piezoelectric response of PFN–PIN–PT is found to be mainly ascribed to the intrinsic lattice strain.
