Lead zirconate titanate (PZT) films 60 {mu}m in thickness have been fabricated using a new sol gel based process. PZT powders are dispersed in a sol gel matrix to form a 0{endash}3 ceramic/ceramic composite. The dielectric properties of these films have been studied as a function of powder concentration, frequency, and temperature. The characteristic Curie point is observed at 420{degree}C. The ferroelectric behavior measured in terms of the remanant polarization (P{sub r}=35 {mu}C/cm{sup 2}) and coercive field (E{sub c}=20 kV/cm) was an improvement over values quoted for thin PZT films but lower than that of bulk ceramic. The piezoelectric properties d{sub 33} (325 pC/N) and d{sub 31} ({minus}80 pC/N) were comparable with those of the bulk ceramic. {copyright} {ital 1997 American Institute of Physics.}
