英文摘要	xPb(Zn0.5Te0.5)O-3-(1-x)Pb(Zr0.5Ti0.5)O-3 (PZnTe-PZT) ceramics were prepared by the solid-state reaction method. The phase structure, microstructure, ferroelectric and dielectric properties and thermal expansion properties were systematically investigated. X-ray diffraction analysis showed the morphotropic phase boundary (MPB) existed at the composition of x = 0.08, which was the coexistence of the rhombohedral phase and the tetragonal phase. The grain size of ceramics decreased rapidly from 10-20 m to 1-3 mu m when the PZnTe was added in. The PZnTe-PZT ceramics at the MPB composition showed the largest high field effective piezoelectric coefficient d*(33) and the lowest strain hysteresis H. The dielectric permittivity and phase transition temperature exhibited strongly compositional dependence. A good linear relation was shown in T-m temperature vs x content and a DPT behavior was found in xPZnTe-(1-x)PZT (x = 0.02-0.08). The thermal expansion properties showed a low thermal expansion coefficient in the low temperature while a high thermal expansion coefficient in the high temperature. Besides, the thermal expansion curve also showed the characteristic of DPT in PZnTe-PZT ceramics.
