The synthesis of compounds was carring out in the system of gadolinium chromite - ferrites doped with bismuth. The citrate-nitrate method was chosen as the synthesis method. An X-ray phase analysis was performed to study the formation of new phases. Based on the results of x-ray phase analysis, it was determined that the obtained compounds in the chromiteferrite system are crystallized in orthorhombic syngony with the Pbnm(62) spatial group. It is showing that when nitric acid is using as a precipitator, can be obtaining single-phase powders. In addition, the structure and parameters of elementary cells of synthesized chromite - ferrites were determining by x-ray phase analysis. The shapes and sizes of the resulting manganite powders determined by electron microscopy. According to the results of the scanning electron microscope, the powders of synthesized chromite-ferrites consist of crystals from 184.3 nm to 3.02 microns.
