A piezoelectric ceramic material, the multilayer component and process for producing the ceramic material

The invention relates to a piezoelectric ceramic material of the general composition ABO¶3¶ with at least a portion of the PZT of a composition according to the invention with Cu cations. The proportion of Zr and Ti cations depending on the content of Cu cations selected such that the ceramic material is set to the morphotropic phase boundary. The invention provides further a method for producing such a ceramic material.
