The results of the crystal structure studies by method X-ray diffraction and Mössbauer effect and the microstructure analysis by high resolution transmission electron microscopy of solid solutions of the (1-x)PbFe1/2Nb1/2O3-xPbFe2/3W1/3O3 system are presented. X-ray diffraction and transmission electron microscopy studies at room temperature reveal the presence of extended planar defects - crystallographic shift planes in the crystal structure of the solid solutions (1-x)Pb(Fe1/2Nb1/2)O3-xPb(Fe2/3W1/3)O3 system. The structure of the solid solutions (1-x)Pb(Fe1/2Nb1/2)O3-xPb(Fe2/3W1/3)O3 system is demonstrated to comprise regions of disparate chemical composition, as evidenced by a range of techniques.
