The results of internal friction background examined in fine-grained lead zirconate titanate PZT ceramics are presented. The aim of the study was to describe the influence of change in concentration of the lead titanate on the internal friction background. The internal friction examinations were performed using modern automatic frequency relaxator of the RAK-3 type at 293 K. PZT ceramics of the chemical composition PbZrO3-PbTiO3 with PbTiO3 concentration ranging from 25% to 75% were the examined material. The nanopowders were prepared by the sol-gel method. PZT ceramics were obtained by the conventional sintering method. The influence of the changes in the structure of ceramic materials on the internal friction background was reported. SEM images of the domain structure were used to describe the obtained results.
