    • Abstract


      Material series with compositional formula Ba1.0–𝑥Pb𝑥Ti0.90Zr0.10O3 (0 ≤ 𝑥 ≤ 0.20, in steps of 0.05) were prepared by conventional solid state method. All the samples were subjected to X-ray diffraction (XRD) studies and found to be single phase with perovskite structure. SEM measurements were done in order to collect micro-structural information. Different transition temperatures were found to depend on the Pb content. Tetragonality (𝑐/𝑎) and Curie temperature (𝑇c) increase with increase in lead content 𝑥. Dielectric properties were studied as a function of temperature and frequencies.
