采用钛酸丁酯和醋酸铅作为原料，通过溶胶－凝胶（Ｓｏｌ－Ｇｅｌ）方法合成了纳米级ＰｂＴｉＯ３超细粉末。实验结果表明：采用Ｓｏｌ－Ｇｅｌｌ方法可以制得纯度为含ＰｂＴｉＯ３，９９．６７ｗｔ％，平均粒径为６０ｎｍ的高纯、超细、粒径分布范围窄的ＰｂＴｉＯ３粉末。ＰｂＴｉＯ４干凝胶在４００℃下热处理２ｈ后，可以得到结晶程度很高的纳米级ＰｂＴｉＯ３超细粉末。同时通过对醋酸铅（Ｐｂ（Ａｃ）２·３Ｈ２Ｏ）脱水方法的探讨，得出在１９０℃下加热数小时可以有效地脱去醋酸铅中的结晶水。
Nanosized PbTiO3 ultrafine powders were synthesized by sol-gel method using butyl titanate and lead acetate as raw materials. The experimental results show that PbTiO3 powder with purity of PbTiO3, 99.67wt% and average particle size of 60nm can be obtained by Sol-Gell method. PbTiO4 xerogel after heat treatment at 400 ℃ 2h, you can get a very high degree of crystallization of nanoscale PbTiO3 ultrafine powder. At the same time, the dehydration of lead acetate (Pb (Ac) 2 · 3H2O) was discussed. It was found that the crystallization of water in lead acetate could be effectively removed by heating at 190 ℃ for several hours.
