The paper presents the results of the Bi₅Ti₃FeO₁₅ multiferroic phase stability analysis during high-energy ball milling aimed at obtaining fine dispersion ceramic powder. The X-ray diffraction and transmission electron microscopy methods were used to analyse the structure and verify the degree of crystallite dispersion. Structural data analysis was carried out using the Rietveld method. To carry out the analysis of the morphology, the scanning electron microscopy was used. The results that were obtained showed that the high energy ball milling process results in the decomposition of the initial ceramics, where finally Bi₅Ti₃FeO₁₅ and Bi are obtained. An increase in the proportion of the amorphous phase and an increase in the dispersion of the grains and crystallites of the powder that occurs with an increase in the milling time were observed.
