► The liquidus temperature in the ternary Cu–Sb–Sn system was determined by DTA/DSC technique. ► Experiments were carried out along three isopleths x Cu = 0.8; x Cu/ x Sn = 1.22 and x Sb/ x Sn = 1. ► The measured liquidus temperatures are lower than those calculated from respective binary systems by Muggianu approximation method. In this study the liquidus temperature in the ternary Cu–Sb–Sn system was determined by using DTA/DSC experimental technique. Experiments were carried out along three sections of the ternary system assuming x Cu = 0.8; x Cu/ x Sn = 1.22 and x Sb/ x Sn = 1, respectively. The liquidus temperatures obtained in this study were compared with calculated liquidus lines. Muggianu approximation method was used to predict respective isopleths along chosen cross-sections. It was found that measured liquidus temperatures are lower than those calculated from respective binary systems using CALPHAD formalism.
