Abstract

In this study, PZT type ceramics with a general formula Pb1-xBax(Zr0.52Ti0.43(Al0.5Sb0.5)0.05)O3 where (x = 0.00, 0.02, 0.04, 0.06, 0.08, and 0.10) were elaborated by the solid-state reaction method. The main objectives of this study focus on the evolution of structural and electrical properties in the region of the Morphotropic Phase Boundary MPB, the effect of barium substitution, the temperature, and the frequency on electrical properties are also investigated. Different techniques were used to characterize the obtained samples such as X-ray diffraction XRD which shows that the results confirm the high purity of prepared samples without any secondary phase and also indicate the coexistence of both the tetragonal and rhombohedral phases. All the absorption bands corresponding to the perovskite structure are exhibited by The Fourier Transform Infrared spectroscopy FTIR. The Curie temperature TC decreased with increasing Ba2+ content. Furthermore, the effect of the temperature, frequency, and composition on the AC conductivity and dielectric properties demonstrated interesting values
