摘要 水热合成锆钛酸铅(PZT)微晶体,研究了锆钛酸铅微晶体的晶体结构、晶粒形态随水热反应温度的变化规律。研究结果表明,当水热反应温度从125℃变化到200℃时,均有效合成四方晶相的钙钛矿结构的PZT晶体;随着水热反应温度的升高,PZT晶体的四方度(晶格参数c/a比)减小,晶粒尺寸减小,颗粒尺寸增大,晶体颗粒由立方体状逐渐变为球状。 The lead titanate-zirconate（PZT）crystallite was hydrothermally synthesized,and the crystal microstructure and particle morphology of PZT was investigated.The results suggest that the PZT crystallite synthesized effectively with perovskite structure and tetragonal crystal system when temperature increases from 125 ℃ to200 ℃.With the increase of temperature,crystal grain and tetragonality decrease,particle size increases,and particle morphology change from cubic to sphere.
