Doped manganites La1-xBixMn1-yFeyO3-δ(x=0.0-0.3; у=0.0-0.5, Δх, у=0.1) with perovskite-like structure were sintered by solid state reaction and solution method. It was determined by X-ray diffraction that sintered samples have rhombohedral symmetry (S.G. R-3c). The parameters of unit cell were calculated. The morphology of briket was investigated by scanning electron microscopy. It was found that sintered sample is homogeneous, porous and grains are formed by different size. Elemental composition was checked by atomic emission spectroscopy. Additional studies were performed by TG/DSC and laser diffraction (analysis of size distribution of particles).
