Preparation of Coprecipitated Ferroelectric Ceramic Powders by Two‐Stage Calcination

Bruno A. Menegazzo, J. A. Eiras

Abstract

A coprecipitation method is described for preparing ferroelectric ceramic powders. The process is based on source solution preparation for coprecipitation after previous calcination of the constituent oxides or carbonates. Rhombohedral PZT 53/47 could be obtained by this method after calcination at 850°C. In addition, PLZT 9/65/35 was prepared by the same method.
