Generalized model concepts describing the formation of dispersed inclusions of new phases of different stoichiometric composition at the interfaces in polycrystalline films of multicomponent ferroelectric oxides due to the processes of bulk diffusion, grain boundary segregation and interaction with the substrate are described. The aim of the work is an experimental study of the formation of inclusions of «impurity» phases in ferroelectric oxides on the example of polycrystalline films of lead titanate zirconate and strontium bismuth tantalate.
Key words: interfaces, complex oxides, polycrystalline films, phase formation, nonstoichiometry.
