Abstract

A hard lead zirconate titanate (PZT) ceramic has an ABO3 structure with A sites and B sites. The PZT ceramic is doped with Mn and with Nb on the B sites and the ratio Nb/Mn is <2. A piezoelectric multilayer component having such a PZT ceramic and also a method for producing a piezoelectric multilayer component are also disclosed.
