摘要
采用固相合成法制备 0 .0 5Ba(Cu1/ 2 W1/ 2 )O3 - 0 .95PZT三元体系压电陶瓷 ,研究了烧结温度对压电陶瓷压电性能的影响 ;通过XRD和SEM测试发现材料仍为钙钛矿结构 ,显微分析表明晶粒之间结合紧密 ,颗粒大小均匀 ;实验结果表明 ,压电陶瓷的压电系数d3 3 为 6 0 5pC/N ,机电耦合系数Kp为 0 .37左右 ,机械品质因数Qm 为 6 0。
Ba(Cu 1/2W 1/2)O 3-0.95PZT piezoelectric ceramics was synthesized by use of the conventional powder processing technique, and the influence of sintering temperature on its piezoelectric properties was also investigated. The different compose materials are studied by means of XRD and SEM. The modified PZT material still has a perovskite structure. SEM analysis indicated that the crystal grains integrate densely and the grain size is uniform. The results indicated that the d 33、K p、Q m of 0.05Ba(Cu 1/2W 1/2)O 3-0.95PZT were 605?pC/N, 0.37 and 60 respectively.
