Abstract
High-durability lead zirconate titanate (PZT) ceramics were developed in this study to improve both coercive field and mechanical strength under operation. Coercive field and displacement under preloading in PZT was increased by adding an elemental acceptor into B-sites. Mechanical strength was increased by obtaining a small grain size through a lowered sintering temperature using a pulverizing process. The temperature dependence of capacitance was decreased by transformation to tetragonal phase. The present investigation resulted in the development of high-displacement and high-durability PZT compositions.
