Abstract:

Cube-shaped PZT single crystals with PZPT5545 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 120kVcm.
