【摘要】 本文叙述以前驱物Ｐｂ（ＯＨ）＿２、ＺｒＯ（ＯＨ）＿２和ＴｉＯ（ＯＨ）＿２为原料，在２Ｌ高田釜内水热合成、制备功能性压电陶瓷微粉ＰＺＴ的过程．就水热过程的主要影响因素碱度、温度和时间进行了研究和讨论。在低于２００℃，２ｍｏｌ／ＬＫＯＨ，２ｈ条件下，成功地合成该粉体。经Ｘ－衍射和电子显微镜检测分析，该产物是一种平均粒径小于０．３μｍ的立方晶体，具有良好的田电效应值。更多还原

【Abstract】 The hydrothermal preparation process of fine PZT powder in a 2 liters autoclave with the precusors of Pb（OH）₂,ZrO（OH）₂ and TiO（OH）₂ was described in this paper.The effect of the alkali concentrations,tempera-tures and time as the main variables,on the hydrothermal process was stu died and discussed. Fine PZT polvder was successfullY synthesized under the conditions of200C and lcss,2 mol/LKOH and 2 hours.The examination resu1ts of XRD,SEM and TBM show that the PZT powder is a kind of cubic crystallite with an average diameter less than 0.3 microns and has good piezoelectricity value.更多还原
