摘要
(1-x)[Pb(Mg1/3Nb2/3)O-3-PbTiO3 (65/35)]-xPbZrO(3) (PMN-PT-PZ) ceramics near morphotropic phase boundary with 0 <= x <= 0.10 were synthesized via the conventional solid-state reaction method. X-ray diffraction and variable temperature dielectric property characterization indicated that the rhombohedral to tetragonal phase transition temperature (T-rt) increased linearly with the increase of PZ constant. The composition and temperature dependence of their ferroelectric and pyroelectric properties were also investigated. The results showed that there appeared mutation for remnant polarization, coercive field, as well as pyroelectric coefficient at the temperate range near T-rt, which was ascribed to the reorientation of dipoles caused by the rhombohedral tetragonal phase transition.
