耐高温PNN-PSN-PMN-PZT压电陶瓷的制备及器件性能研究
It is widely believed that the application of PMN–PT single crystal will greatly improve the performance of devices or systems and even trigger a revolution in related fields [2–4]. However, the poor polarization stability of PMN–PT single crystals, which has been acknowledged by researchers,...
如r.pramanik[1]等人通过控制晶粒尺寸制得的pmn-pt的kp值只有0.7;高翔宇[2]等人制得的pnn-pzt压电陶瓷的kp值仅有0.63。而对于无铅压电陶瓷,其kp值更低,赵志浩[3]等人制备的织构化bnt-bkt-bt陶瓷的kp值仅有0.31;srideviswain[4]等人制得的nbt-bt陶瓷的kp仅能达到0.21。目前,在含铅和无铅压电陶瓷中,添加...
