Abstract

Piezoelectric composites prepared by firing ceramic lead zirconate titanate (PZT) powders within a PZT sol gel have a two phase structure in which both phases have high permittivity. Dielectric measurements reflect the presence of the two phases and of interfacial layers between the phases and at the electrodes. The system has been modelled as a) a composite dielectric and b) a multi-layer capacitor with some complex components. The frequency dependent response of composites, sol gel derived films and a bulk ceramic is compared.
