Power Dissipation during Dielectric Loop Evolution in PZT Ceramics

Abstract

The study results of switching processes in non-polarized lead zirconate titanate ceramics are given. The dielectric hysteresis loop losses arising during exposure of the samples in alternating fields of constant amplitude are analyzed. It is shown that the formation of the loop is followed by the sample heating in fields where switching processes are observed.
