The study of anomalies in the pzt material

Lead zirconate titanate PbZr0.52Ti0.48O3 (PZT52) sample was prepared using the conventional solid state reaction. The nanosized PZT52 sample shows a mixture of phases tetragonal and rhombohedral, and a grain size of about 31 nm calculated from the Scherrer equation. The sample sintered at 900 °C for 4 hours showed a diffuse maximum of the permittivity of about 5354 located at the temperature of 412 °C. XPS analysis of the sample reveals the presence of contaminants, and a composition, after sintering, similar to the nominal one.
