Structure and electrical properties of (1 − x)Pb(Zn0.2Ni0.8)1/3Nb2/3O3xPbTiO3 ceramics with x = 0.24–0.38 were examined in detail. X-ray diffraction measurements reveal that all samples are in pure perovskite phase, and most of them lie within the morphotropic phase boundary (MPB) region. The dielectric behaviors of all compositions are characterized with diffuse phase transition and frequency dispersion. The variable power law and the Vogel–Fulcher relation have been used to describe such dielectric behaviors. The highest dielectric constant and the largest piezoelectric coefficient are simultaneously observed when x = 0.30. The variation of the ferroelectric property with PT content is also discussed.
