Abstract:
|
The aim of this work is to study the dependence of the linear and non-linear dielectric, piezoelectric and mechanical coefficients on the Ti fraction in PZT ceramic compositions near the morphotropic phase boundary. The dependence of these coefficients with the defect concentration is also analysed. Special attention is given to the extrinsic piezoelectric measurements related to the domain wall movement. Since the non-linear behaviour is produced by the extrinsic phenomenon, the non-linear measurements provide a good extrinsic characterization of materials. In all cases the physical explanation of the behaviour is sought. |
