| Abstract: | In the present work, a bulk study of lead zirconate titanate ferroelectric PbZr0.52Ti0.48O3 is performed through low - temperature x - ray - diffraction (XRD) and fatigue. The XRD pattern reveal the existence of superlattice reflections, which is related to the changes of the material's microstructure. Fatigue properties of PZT were studied systematically. Experimental results exhibited that the sample is almost fatigue free at low temperature. It must be the contribution of antiphase boundaries, which can cast light on the application of PZT. |
