AC Impedance Spectroscopy Study of BaZr_0.10Ti_0.90O₃ Ceramics

Abstract

BaZr_0.10Ti_0.90O₃ ceramics have been prepared by a solid-phase reaction from simple oxides and carbonates by a conventional method. The SEM and EDS studies revealed that the investigated sample was perfectly sintered and was chemically homogeneous. Impedance spectroscopy measurements showed both intra- and intergranular effects and electric relaxation of non-Debye type.
