It was established that solid-phase interactions between the two oxides lead to the formation of phases (B-Ln₂O₃, LnFeO₃, Ln₃Fe₅O₁₂, Fe₂O₃). The boundaries of the regions of homogeneity of solid solutions formed in the systems were determined. Nanopowders synthesized based on the perovskite-type phase (LnFeO₃) by the Pechini method and heterogeneous precipitation from nitrate solutions, employing a combination of physicochemical methods, are single-phase with a perovskite-type structure. It was established that both the method of synthesis of nanopowders and the choice of initial components significantly affect the structure and properties of the resulting material.
