Research on Wct Synthesis for Preparing PZT Ultrafine Powders

Through wet chemical synthesis,ultrafine PZT powder can be obtained with high-purity,uniform grain size and precise control of composition. This paper gives a overview to the common methods,main principle and process conditions for preparing PZT ultrafine powder by wet chemical synthesis. Moreover,the advantages and shortages of some methods are reviewed for PZT powder preparation,such as Sol-Gel,coprecipitation and hydrothermal synthesis.
