The article presents the study of the transformation conditions of bismuth (III) selenium in the aquatic environment from the interaction of bismuth oxide with elemental selenium. The dependence of the formation of the compound on temperature, pH of the medium, the amount of reducing agent was studied and the reaction equation of the process was compiled. The physical and chemical properties of the obtained compounds were determined by TQ, DTA, RFA, and chemical analysis methods. By thermogravimetric analysis, the Bi: Se ratio in the sample was 90.65: 49.98. The melting temperature of the sample was determined at 705 0C by the differential thermal analysis. X-ray structure analysis confirmed the individuality of the sample. Thus, the intensity and angle values of the peaks obtained in the diffractogram corresponded to the reference values. Based on the above, it was clarified that the composition of the sample corresponds to the formula Bi2Se3.
