Lead titano-zirconate (PZTx), with different concentrations in Zr (x ranging from 26 to 78), was synthesized by the conventional solid state reaction route. Pellets annealed at 900°C during 4 hours have been characterized by X-Ray Photoelectron Spectroscopy (XPS). Determination of the constituents at the surface of the samples from XPS analysis has given good agreement with nominal compositions.
