Abstract
PZT ceramics were statically and dynamically evaluated to examine the relationship between domain structures and electrical properties. We investigated the domain structures of tetragonal, M.P.B. and rhombohedral PZT ceramics at various poling fields to measure the poling field dependence of the crystal orientations and electrical properties as a statical evaluation. Furthermore, responses to repeated voltage pulses applied to the ceramics were measured by a high voltage test system as a dynamical evaluation. Through these evaluations, we could clarify the domain behavior for the 90° (71° or 109°) domain rotation, switching and clamping of 180° domain, and transient phenomena on the domain orientation.
