中文摘要：

以丙醇锆（C12H22O4Zr）、醋酸铅（Pb（CH3COO）2·3H2O）、异丙醇钛（Ti{OCH（CH3）2}4）为原料，采用改进的溶胶-凝胶（Sol—Gel）工艺，研究了不同的热处理制度对于Pb（Zr0.52Ti0.48）O3粉体的物相形成、晶粒尺寸及颗粒分散度等的影响。实验结果表明，Sol—Gel法制备PZT粉体，预结晶温度段，改变烧结时间，对于粉体颗粒的尺寸影响不大；结晶温度段，改变结晶时间或结晶温度，会对颗粒尺寸产生较大的影响。

英文摘要：

By using the zirconium n-propoxide （C12 H28 O4 Zr） ,lead acetate （Pb（CHa COO）2·3He O）, isopropyl titanate （Ti{OCH（CHa）2 }4 ） as the starting materials,the PZT powders were prepared by an improved Sol-Gel technology. The effects of different annealing process on the phase formation, grain size and particle dispersion of PZT powder were investigated. The results showed that the change of the sintering time at the stage of pre-crystallization had no obvious influence on the particle size;however the change of the crystallization time or crystallization temper ature at the stage of crystallization would lead to dramatically changes on particle size.
