The results of X-ray diffraction analysis of the solid solutions in the (1- x )Pb(Fe 1/2 Nb 1/2 )O 3 – x Pb(Fe 2/3 W 1/3 )O 3 systems with x = 0.0÷0.5, investigating their microstructure and measurements of dielectric characteristics are presented in this paper. The critical influence of Pb(Fe 2/3 Wy 1/3 )O 3 on the crystallization of solid solutions and the nature of grain boundaries is established. A sintering mechanism of the solid solutions is defined. Correlations between the dynamics of the crystalline and grain structures and the dielectric properties of investigating solid solutions are established.
