FOR LEAD

Abstract

The affect of A120 3 and Bi20 3 on the densification and electrical properties of lead zirconium titanate (PZT) solid-solution was studied. Samples were hot pressed at 850°C under 18,000 psi for two hours. was shown to form a low melting liquid with PbO that had minimal affect on the densification rate and electrical properties. The liquid segregated into pockets that did not wet the PZ'I' grain. was shown to lower the temperature at which increased densification occurs as well as lower the coercive field, remna~t polarization, and saturation polarization as compared to the undoped material.
