“…However, for liquid phase the information is lack [13][14][15][16][17][18][19][20]. In our work the modeling was executed in atmosphere of argon at the common pressure of P = 10 5 Pa and temperature and concentration intervals, corresponding to regions of liquid state on phase diagrams of binary GaSb, In-Sb, Al-Sb systems [11,12]: Ga-Sb, In-Sb systems: Т = 1000 -1600 К, 0 х Ga(In) 1, Al-Sb system: T = 1300 -1700 К, 0 х Al 1, where х Ga, х In and х Al is initial content of gallium, indium and aluminum in the melt (mole fraction), respectively.…”
