Procedure

Lead acetate hydrate, Pb(CH3COO)2H2O, is dissolved in 2-methoxyethanol and is dehydrated at 110° C. under vacuum to provide lead acetate. A solution of zirconium n-propoxide, Zr(n-OC3H7)4, and titanium isopropoxide, Ti(i-OC3H7)4 in 2-methoxyethanol is prepared. The zirconium-titanium solution is then added to the lead acetate solution and the mixture is refluxed for 2 to 3 hours at 100° C. and is then distilled to provide a PZT polymer precursor of the formula Pb(Zr0.52Ti0 48)O3.
