Experimental investigation and thermodynamic prediction of the Ga–Sb–Sn phase equilibria

Abstract

Abstract Optimized thermodynamic data, successfully used for phase diagram calculations of constitutive binary systems, were used for prediction of phase equilibria in the ternary Ga–Sb–Sn system. The projection of the liquidus surface, invariant equilibria and three vertical sections with molar ratios Sb:Sn = 1, Ga:Sn = 1 and Ga:Sb = 1 of the Ga–Sb–Sn ternary system were calculated using the CALPHAD method. Alloys, situated along three selected vertical sections, were investigated using differential scanning calorimetry. The experimental phase equilibria data from this work and literature were compared with calculation results.
