Abstract

The ceramics, (0.65 + y)Pb(Zr_0.47Ti_0.53)-(0.35- y)Pb[(Ni_1-xZn_x)_1/3Nb_2/3]O ₃ have a morphotropic phase boundary (MPB) of pseudo-cubic and tetragonal structures. Their ε₃₃^T/ε₀ value considerably decreased on the pseudo-cubic side of the MPB composition, but the d₃₃ and k_p slowly decreased on both sides of the MPB. Therefore, the maximum transduction coefficient (d₃₃ * g₃₃) was obtained from the composition on the pseudo-cubic side of the MPB, because g₃₃ is given by d₃₃/ε ₃₃^T. This result could be applied to other systems containing an MPB of pseudo-cubic and tetragonal structures. Furthermore, a d₃₃ * g₃₃ value of 20 056 × 10^-15 m²/N, which is the highest value reported so far for polycrystalline ceramics, was obtained from the 0.68Pb(Zr_0.47Ti_0.53)O ₃-0.32Pb(Ni_0.6Zn_0.4)_1/3Nb _2/3O₃ ceramic.
