Fabrication and Piezoelectric Properties of 1-3 Composite Sheets Consisting of Highly Oriented PZT Single Crystal Grains

Abstract

Cube-shaped PZT single crystals with PZ/PT=55/45 composition were grown in a relatively uniform size distribution around 80 micrometers by a PbO-flux method. The PZT grains obtained were mixed with liquid polyimide resin and rolled on a glass plate to fabricate 1-3-type composite sheet. This rolling process resulted in a high orientation of the PZT grains as the ?h00! are parallel to the substrate plane. The degree of grain orientation reached about 90%. After heating at 180 degrees C, the composite sheet showed a well-defined DE hysteresis loop due to the dielectric property of PZT grains. The longitudinal field-induced strain was 0.2% at 120kV/cm.
