Аннотация:Experimental data are used to build a thermodynamic model for the liquid phase of the Bi–Ga–Zn system. The model and those of other phases are used to determine coordinates of the invariant points of the Bi–Ga–Zn system and the projection of its liquidus surface. The polythermal cross-section of the system’s phase diagram is calculated for compositions xBi/xZn = 1, along with the isothermal cross section at 573 K
