0.05Pb(Fe1/2Nb1/2)O3-0.05Pb(Ni1/3Nb2/3)O3-0.90Pb (ZrxTi(1-x))O3 (abbreviated as PFNN–PZT) quaternary piezoelectric ceramics with varying Zr/Ti ratio, which locate in the vicinity of the morphotropic phase boundary (MPB), were prepared by a conventional mixed-oxide route. The phase structure, the piezoelectric and dielectric properties of the system were investigated. X-ray diffraction patterns indicate that the MPB of the tetragonal and rhombohedral phase lies in the range 0.49 < x < 0.53. Both the piezoelectric coefficient (d31) electromechanical coupling factor (kp) and the dielectric constant (er) reach the maximum values at x = 0.51. this reflects the transition from tetragonal phase to rhombohedral phase, which makes this material a good candidate for high-power multilayer piezoelectric transformer applications.
