In this paper the mechanism of the formation of gaseous inclusions in the liquid phase on the example of Bi 2 Te 3 ‐Bi 2 Se 3 system is considered. The thermodynamic analysis for the model scheme of melting has been carried out. It is shown that the time dependence of the pressure and composition of gaseous phase is determined by establishment of equilibrium between liquid and gaseous phases in the system. The results of numerical computation give a quantitative evolution of the size of critical gaseous nucleus in the Bi 2 Te 3 ‐Bi 2 Se 3 melt with the time and its dependence on the height of melt column.
