Abstract
The present study aims to fabricate PZT piezoelectric ceramic sheets which perform at a high capacity in low electric fields for developing actuators with large displacement. This paper describes the fabrication procedures of PZT sheets and their results. As the results of XRD analysis and SEM observations of precalcined powders showed, 800°C was the appropriate calcination temperature for Pb(Zr0.3Ti0.7)O3 and Pb(Zr0.65Tia0.35)O3 composition. Green sheets with uniform thickness distribution were fabricated by Doctor Blade process with slurries 2000-5000cp in viscosity. The size of the fabricated green sheets was 135±5μm and 50±2μm in thickness, 180mm in width, and 5m in length, with a density of 4.7-5.1 g/cm3. Additives, such as solvent, binder, plasticizer and dispersant were completely eliminated by heat treatment at 500°C. The PbO excess atmosphere sintering at 1000°C produced PZT sheets which have perovskite phases only, and were well densed.
