Abstract (en)
[origin: WO2019020265A1] The invention relates to a hard lead-zirconate-titanate (PZT) ceramic of general structure ABO3, which has A areas and B areas, wherein the PZT ceramic has a doping on the B areas with Mn and Nb with the ratio Nb/Mn < 2. The invention also relates to a piezoelectric multilayer component comprising such a PZT ceramic and to a method for producing a piezoelectric multilayer component.
