A method of preparing a sol of lead zirconium titanate, known as PZT, of formula PbZrxTi(1−x)O3 with 0.45≰x≰0.7, comprises the steps of: (a) preparing a concentrated sol in a diol, the sol comprising a titanium-based precursor, a zirconium-based precursor, and a lead-based precursor; (b) placing the concentrated sol at ambient temperature without agitation, until a sol is obtained having a constant viscosity as a function of time; (c) diluting the sol obtained in (b) with a solvent compatible with the diol used in step (a). The sol is useful for preparing PZT-based films for use in the electronics field. |
