Effect of Processing and Special Compositional Variations on the Microstructural and Electrical Behavior in the Lead Zirconate Titanate System.

Abstract

Recently lead zirconate titanate compositions (because of their high electro-mechanical coupling and polycrystalline nature) have been employed as substrates for interdigitally poled transducers. A desire was expressed to try to further develop a ceramic which could be readily polished and poled; in addition to exhibiting characteristics which would make it suitable for a (surface acoustic wave) SAW device (more specifically, low power loss over the operating frequency, high coupling, and relatively small grain size). The base composition was selected from the work done by Haertling and Land on the ternary system La-PbZrO2-PbTiO2 to achieve an optimization of dielectric constant, coercive field, planar coupling and remnant polarization.
