Two samples of nanostructuredPb(Zr0.52Ti0.48)O3 ceramic powders were prepared by hydroxide co-precipitation and aqueoussolution method (water bath technique). The XRD pattern of theĀ  powder exhibited the presenceof major tetragonal and minor rhombohedral crystalline phases indicating the mixed-phasecomposition, which is close to the morphotropic phase boundary (MPB). SEM analysis revealedgood homogeneity of the materials. The plot of real part versus imaginary part of the compleximpedance was observed nearly a semicircle, indicating that the samples are good dielectricmaterials, whose resistance decreases considerably with the increase of temperature. Similar tothe normal ferroelectric materials, the dielectric constant () of PZT has been found to be increasinggradually with temperature and attains a maxima (max). The detailed analysis for the shift in peaktemperature and dielectric constant were carried out. ER -
