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, 0.04, and 0.08) were elaborated by the solid-state reaction and studied for their structural and dielectric properties in the region of the morphotropic phase boundary (MPB). 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 scanning electronic microscopy (SEM) shows that the mean grain size was found between 2,84 and 2,14 µm, the Curie temperature (TC) decreased with increasing Ba2+ content. Furthermore, the effect of the temperature, frequency, and composition on the dielectric properties demonstrated a maximum value of the dielectric constant ε max = 38800 at 1 kHz when X= 0.08.
