Formkoerper auf der Basis von PZT (Pb(Zr,Ti)O3, Bleizirkonat-Bleititanat), Verfahren und Zwischenprodukt zu deren Herstellung

The invention relates to moulded parts, fibres and coatings based on PZT (lead zirconate-lead titanate) which are obtained by adding organic zirconium compounds of the formula Zr(OR->1 )<-4 (I) and organic titanium compounds of the formula Ti(OR->2)<-4 (II) separately or together and refer to 1 Mol of the compounds (I) plus (II) with 0 to 4 Mol of an alcohol or a mixture of alcohols of the formula R->3 -X-R->4-OH and/or R->3 -CX-R->4 -OH (IV), that the resulting mixture(s) or compounds (I) and (II) are added separately or together and related each to 1 to 3 Mol of the compounds (I) and (II) with 1 to 3 Mols of one or several carbon acids comprising 2 to 10 carbon atoms, that everything related 1 Mol of the compound (I) plus (II) is mixed with 1 to 1.5 Mol of one or several Pb(II) and/or Pb(IV) carboxylate that the mixture is subjected to a hydrolitic condensation, that the volatile constituents are removed until a compound which is solid at room temperature results, that the solid mass is heated until a highly viscous liquid is obtained, that the liquid is processed into moulded parts, fibres or coatings, and that they are heated to temperatures of at least 500 degrees Celsius
