摘要：

in the present work the results of preparation of the multiferroic Pb(Fe1/2Nb1/2)O-3 (PFN) ceramics were presented. A synthesis of the PFN ceramics powders was carried out via a wet chemical route, by the sol-gel method. The densification process of ceramic powders was made by using the free sintering method (a conventional sintering) or by the hot uniaxial pressing method. Measurements of the SEM micrographs of fracture surfaces, dielectric and electric conductivity properties were performed. The investigations have shown the influence of densification process on the microstructure and physical properties of ceramics obtained in such a way, as well as usable parameters and a character of electric conductivity on which PFN is dependent.
