摘要：

A strain-induced structural phase transition and its subsequent effect on the piezoelectric properties of BZT-BCT-x CeO2 (x=0-0.1wt%) ceramics have been reported in this manuscript. BZT-BCT-xwt% CeO2 lead-free piezoceramics were successfully been prepared using sol-gel method. X-ray diffraction spectra of BZT-BCT-xwt% CeO2 (x=0-0.10wt%) ceramics showed a purely single-phase perovskite structure and a change in crystal structure between tetragonal and rhombohedral phases with increasing CeO2 content. The strain-induced structural phase transition has resulted in excellent piezoelectric properties, d(33)=673 pC/N, k(p) 56%, and T-c=110 degrees C for BZT-BCT-0.08wt% CeO2 ceramics. Greatly improved temperature stability of the piezoelectric properties has been observed over a temperature range between 20 degrees C and 90 degrees C. The ferroelectric-paraelectric transition temperature, T-c obtained in this study is 17 degrees C higher than those reported earlier.
