A method for synthesizing ferroelectric thin films of lead zirconate-titanate (PZT) and lead-lanthanum zirconate-titanate (PLZT) by a modified sol-gel technique is reported. The following chemical compositions with the Zr/Ti ratio were obtained: PZT 65/35 and PLZT 6.5/65/35. Thin films, prepared from acetate and alkoxide precursors of La, Pb, Zr and Ti, were deposited on stainless steel and MgO substrates by spin coating. Crystallization of PZT-based electroceramic thin films was performed by thermal annealing at the temperature range of 550-700 st.C. The structure of the thin films was investigated by X-ray diffraction. The formation of the perovskite-type structure was confirmed. Microstructure was investigated by the optical microscopy. Technological conditions of the preparation of thin films were optimized.
