Abstract

(1-x)Pb(Zr0.47Ti0.53)O3-xPb[(Ni 0.6Zn0.4)1/3Nb2/3]O3 [(1-x)PZT-xP(NZ)N] ceramics with 0.22 ≤ x ≤ 0.45232 have the tetragonal-pseudocubic morphotropic phase boundary (MPB). Their ε33 T0 values considerably decreased but their d33 values slowly decreased on the pseudocubic side of the MPB. Therefore, high d33 × g33 values were obtained from a composition on the pseudocubic of the MPB because g33 is given as d3333 T. In particular, a very high d33 g33 value of 20 134 10-15 m 2/N was observed from the 0.7PZT-0.3P(NZ)N ceramic sintered at 1000 °C for 2 h, which had a pseudocubic structure. The 0.7PZT-0.3 P(NZ)N ceramic sintered at 950 °C also exhibited a similar d33 × g 33 value of 20 179 10-15 m2/N but it considerably decreased to 12 474 10-15 m2/N for the 0.7PZT-0.3P(NZ)N ceramic sintered at 1100 °C for 2 h, which can be explained by the increased ε33 T value that resulted from the increased grain size. The grain size of this ceramic decreased as the sintering time decreased, resulting in an increase of the d33 × g 33 value due to the decreasing ε33 T value. The high d33 × g33 value of 19 572 10-15 m2/N was also obtained from the 0.7PZT-0.3 P(NZ)N ceramic sintered at 1100 C for 5.0 min, indicating that grain size is also important for obtaining a specimen with a high d33 × g33 value.
