In this work, we present a comparative study of structural and electrical properties of lead zirconate titanate (PZT) bulk ceramics of composition PbZr0.52Ti0.48O3, prepared from the powders synthesized via sol–gel and solid-state reaction methods. X-ray diffraction (XRD) patterns of the sintered samples are suggestive of the presence of pure perovskite phase. Indexing of diffraction peaks of the samples is done as per monoclinic structure. The average crystallite size for the samples has been calculated using Williamson and Hall (WH) plots. Scanning electron microscopy (SEM) is performed to study the surface morphology of sintered samples. The values of dielectric constant measured at room temperature at 1 kHz are found to be 305 and 1095, respectively, for sol–gel derived and solid-state reaction derived ceramics. Temperature dependence of dielectric constant show that the transition temperature corresponding to ferroelectric to paraelectric phase at 1 kHz for both the samples are same, i.e., 333 °C, but the transition is more diffused in the case of the ceramics synthesized via sol–gel method. Well-saturated P-E hysteresis loops obtained for both the samples at room temperature signify their ferroelectric nature.
