中文摘要：
以醋酸铅[Pb（CH3COO）2^-33H20]、硝酸锆[Zr（N03）4^-5H2O]和钛酸四丁酯[Ti（C4H90）4]为原料，以二乙醇胺（diethanolamine，DEA）为聚合剂．用溶胶-凝胶法制备了锆钛酸铅（PbZrxTil-x03，PZT）纳米陶瓷粉体。研究了DEA对溶胶-凝胶法合成PZT陶瓷粉体的影响。通过Fourie变换红外光谱、热重-差热仪、X射线衍射仪、扫描电子显微镜和能谱仪等对所得到的粉体进行了表征。结果发现：DEA能有效促进钙钛矿相PZT结晶，最佳的DEA体积掺量为10％，430℃便可生成纯相PZT纳米粉体，随着煅烧温度升高结晶性逐渐增强。
英文摘要：
The nano-particles of lead zirconate titanate （PbZrxTil-xO3, PZT） were synthesized by a sol-gel method using Pb（CH3COO）2. 3H2O, ZrCNO3）a.5H20 and Ti（OCaH9）4 as starting materials. Diethanolamine （DEA） was used as a polymerizing agent. The effect of DEA on the sol-gel synthesis of PZT powders was investigated. The product powders were characterized by Fourier transform infra- red spectroscopy, thermogravimetric~lifferential thermal analysis, X-ray diffraction, scanning electron microscopy and energy dis- persive spectroscopy, respectively. The results show that DEA can accelerate the transformation to perovskite, and the optimum con- tent of DEA is 10% in volume. The phase pure PZT nano-particles were synthesized at 430 ℃. The crystallinity could be improved when the calcination temperature was increased.
