IEEE Joint International Symposium on the Applications of Ferroelectrics / International Workshop on Acoustic Transduction Materials and Devices / Workshop on Piezoresponse Force Microscopy (ISAF/IWATMD/PFM), Pennsylvania, United States Of America, 12 - 16 May 2014, pp.5-8
In this study, Zr doped NBT-BZT (94Na(0.5)Bi(0.5)TiO(3)-6BaZr(x)T(1-x)O(3)) (x=0.1) powder was synthesis with solid-state method. The sintering process was carried out at between 1035 to 1180 degrees C in air for 2h. The crystal phase and microstructure of the ceramics were characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). The influence of Zr content on the piezoelectric and energy harvesting performance were investigated and compared with PZT4, PZT5H. Ferroelectric and piezoelectric properties of NBT-BZT ceramics were obtained with impedance/gain phase analyzer. The results showed that, the best electrical properties were obtained at 1150 degrees C. Also, energy harvesting potential of cymbal form of NBT-BZT materials were greater than disc (bulk) form.
