Verfahren zur Herstellung von PZT-Schichten

The invention relates to the field of machine engineering and thick-film technology and relates to a process for the production of PZT coatings as applied in the coating of rollers. The invention is based on the technical problem of avoiding PbO evaporation and the transverse contraction of the PZT coatings, so that such PZT coatings can be applied on substrates using methods of thick-film technology and thus piezo-electric coatings with a thickness of 300 <my>m with high adhesive strength can be produced. The invention solves the technical problem by means of a process for producing PZT coatings by thick-film technology on a substrate whereby the PZT coatings contain simply modified PZT and/or PZT with complex perovskite, by the fact that PZT with a Zr content of X of X >= X<-p + 0.02 where <= X<-p + 0.10 is the Zr content of basic compound at the morphotropic phase boundary which is determined by the K<-r maximum
