摘要：

Perovskite-layer structured (PLS) piezoelectric ceramics have the characteristics of ultra high Curie temperature and good thermal stability, thus PLS ceramics have become one of the hot topics in the field of high temperature piezoelectric ceramics. The present article reviews the research progress on PLS piezoelectric ceramics from the aspects of crystal structure, processing technologies, doping modifications, and forming solid solutions in order to overcome their disadvantages of poor sinterability and low piezoelectricity. Meanwhile, this review summarizes and compares the effects of processing technologies and doping modifications on the sinterability and piezoelectricity of PLS ceramics. Furthermore, the origin of the spontaneous polarization of PLS ferroelectircs is briefly described. The mechanism of ferroelectric phase transition and the approaches to improvement of piezoelectric properties for PLS piezoelectric ceramics are proposed for research work in the near future.
