摘　　要：BNT陶瓷由于具有良好的压电性、高居里温度和烧结过程中无毒、易控制性等优点而倍受青睐。本文介绍了无铅压电陶瓷的研究概况、相变过程及其基本性质、制备工艺,根据已有的研究经验着重对BNT陶瓷掺杂改性进行了探讨,并展望了它的发展前景。BNT piezoelectric ceramics are interested because of their good properties, such as relative larger piezoelectricity, high Curie temperature, easy control and nontoxicity. The current status of the researches of lead-free piezoelectric ceramics, the phase transition, the basic properties and the preparation technologies are introduced in this paper. The doping modification of BNT ceramics is discussed according to the former research experiences. We also predict the development prospects of BNT piezoelectric ceramics.
