Ceramic samples of Barium Zirconium Titanate (BaZr x Ti 1Àx O 3 (BZT)) were synthesized by conventional solid-state reaction method with different concentrations of x (¼ 0:05 (BZT1), 0.10 (BZT2), 0.15 (BZT3), 0.20 (BZT4), 0.25 (BZT5), 0.30 (BZT6)). Phase confirmation of the samples was done by X-ray diffraction (XRD) technique. All the compositions are in cubic structure. XRD pattern was recorded for samples sintered at different sintering temperatures. Lattice parameters increased with addition of Zr þ4 . Doping with Zr þ4 into Barium titanate resulted in interesting changes of electrical properties (dielectric, impedance and ferroelectiricity). The strong influence of Zr doping on the phase transition characteristics of the BZT ceramics was studied from the dielectric response of the samples. Diffusivity of phase transition of the BZT ceramic samples increase with Zr þ4 concentration, indicating changes from normal to diffuse transition to relaxor phase transition behavior. Impedance spectroscopy reveals the presence of temperature-dependent grain, grain boundary effects. Polarization-Electricfield (PE) loop measurements are also done on the samples.

Typical Electrical feature of Musa acuminata colla (common name of commercially available banana) peel was identified as inhomogeneous lossy-dielectric. Considering in this direction, detailed impedance analysis was made at room temperature in the frequency range of 0.001 Hz to 1 M Hz. Impedance relaxation was well-fitted into Gaussian curves. The complex impedance plot, associated with two depressed semicircles, indicates Warburg-diffusion phenomenon. Randles's plot and frequency vs. admittance plot confirm the same. The results were corroborated by Jonscher's Universal law for better understanding of the inhibitor (corrosion-free) nature of the banana-peel.
