|【文章摘要】 Phase pure lead zirconate titanate (PZT) powder was produced via a new aqueous coprecipitation method. A suite of characterization techniques, including FTIR, Raman, X-ray diffraction, SEM as well as nitrogen sorption were employed to investigate the structural evolution of the synthesized and calcined powder. The dried precipitate formed in aqueous phase yielded approximately 80 wt% final product after calcination. The PZT perovskite structure was obtained after calcination at 550 degrees C for 3 h. Milling of the calcined powder reduced the mean particle size from approximately 10 mu m to 2 mu m. With increasing calcination temperature from 550 degrees C to 700 degrees C, both surface area and pore volume decreased while pore size increased from 3.4 nm to 9.8 nm. The bulk density of pelletized samples increased from 4.83 to 7.57 g/cm(3) with increasing sintering temperature from 800 degrees C to 1200 degrees C. Powder processing using this aqueous route is simple and reproducible leading to a method that is readily scalable for industrial applications.
