DEVELOPMENT OF HIGH POWER TEXTURED PIEZOELECTRIC CERAMICS WITH ULTRAHIGH ELECTROMECHANICAL PROPERTIES FOR LARGE DRIVING FIELD APPLICATIONS
Embodiments relate to a piezoelectric ceramic and methods of making the same that is suitable for use as a high-power piezoelectric ceramic, and in particular a piezoelectric ceramic that exhibits both good hard properties and good soft properties. Embodiments involve generating the piezoelectric ceramic via the combination of chemical modification/doping and/or a texturing method so that the piezoelectric material exhibits a large figure of merit, as well as other hard and soft properties. The chemical modification involves Cu and Mn doping a piezoelectric material composition having a relaxor-lead titanate based ferroelectric structure. The texturing involves templated grain growth (TGG) texturing using a BaTiO3 (BT) template.
