Abstract: Within our work a ceramic of the PFN type was obtained by a single stage method and it was subjected to a cobalt modification in the amount of: 1.0, 2.0, 3.0, 4.0 and 6.0 mol%. Studies of the influence of the cobalt admixture on the crystalline structure, microstructure and ferroelectric properties of PFN ceramics were performed. It was shown that the iso-valence PFN admixing with cobalt had a positive influence on the density and ceramic microstructure. Higher cobalt admixtures (above 1.0 mol%) in PFN eliminate pyrochlore phase formation, and at the same time they reduce maximum electric permittivity values. The ferroelectric to paraelectric phase transition in the modified PFN compositions undergoes diffusion.
