ABSTRACT:
Thin films of the lead titanate system expressed by the general formula: Pb(Zr.sub.x Ti.sub.1-x)O.sub.3, where 0.ltoreq.x<1, are produced by (a) preparing a complex alkoxide including at least lead and titanium atoms by a liquid-phase reaction of lead carboxylate with at least one alkoxide of titanium and zirconium alkoxides, (b) dissolving the resultant complex alkoxide in water to prepare an aqueous solution of the complex alkoxide, and (c) immersing a substrate in the resultant aqueous solution to deposit a thin film of the lead titanate system on said substrate by hydrolysis of the complex alkoxide. The resultant thin film may heated to a temperature ranging from 400 to 900.degree. C. to produce thin films with a perovskite structure.
