Abstract
The invention relates to a piezoelectric ceramic material having the general composition ABO3 with at least a proportion of the PZT ceramic having a composition of the invention with Cu cations. The proportion of Zr and Ti cations is selected based upon the content of Cu cations, such that the ceramic material is tailored to the morphotropic phase boundary. The invention further discloses a method for producing a ceramic material of this type.
