Fe掺杂PZT压电陶瓷的制备及其性能研究

Study on the Preparation and Properties of PZT Piezoelectric Ceramics with Fe

采用传统固相反应法制备出了性能良好的Pb1-xFex(Zr0.55Ti0.45)1-x/4O3压电陶瓷,研究了烧结温度、Fe的掺杂量对PZT压电陶瓷的结构和电学性能的影响。结果表明,所制备的PFZT压电陶瓷以四方相为主晶相;当烧结温度为1150℃,保温2 h时试样具有最大的体积收缩率;随着Fe加入量增加,介电常数、压电常数降低,介电损耗逐渐减小。

This paper using the traditional solid-state reaction sintering method make PZTF （Pb1-xFex（Zr0.55Ti0.45）1-x/403, X=0, 0.001, 0.002, 0.003, 0.004 ）piezoelectric ceramic that has good properties. Study the effect of the structure and electrical properties with sintering temperature and Fe doping. As a result that, the PZTF has a boxy phase, when the sintering temperature at 1150℃ , and keep 2 h,the sample has the biggest contractibility, with the content of Fe increase, the dielectric constant and the Piezoelectric constant are conformity with the traditional PZT, the Dielectric loss is decrease.
