The polycrystalline samples having composition Bi0.45Eu0.02Na0.45Pb0.1Zr0.048Ti0.952O3 (BNPZTE-2 abbreviated ahead), Bi0.41Eu0.04Na0.45Pb0.1Zr0.048Ti0.952O3 (BNPZTE-4 abbreviated ahead), Bi0.39Eu0.06Na0.45Pb0.1Zr0.048Ti0.952O3 (BNPZTE-6 abbreviated ahead) had been synthesised using the mixed oxide processing route. The prepared samples were found to be in single phase and crystallize in tetragonal structure. The surface morphology suggests the high density grain growth in all samples. The electrical behavior (dielectric, impedance, and modulus) of the prepared samples collected at various temperatures and frequencies. The value of activation energy had been evaluated from the temperature dependent conductivity plot. The grain and grain boundary contribution to the polarization process have been depicted from the impedance analysis. The parallel plate capacitor structure was proposed to unveil the influence of applied electric field on the excitation of samples. The prepared samples will find its application in the filter application (noise removal) or buffering circuit.
