Liquidus determination in the Cu-Sb-Sn ternary system

► The liquidus temperature in the ternary Cu-Sb-Sn system was determined by DTA/DSC technique. ► Experiments were carried out along three isopleths xCu = 0.8; xCu/xSn = 1.22 and xSb/xSn = 1. ► The measured liquidus temperatures are lower than those calculated from respective binary systems by Muggianu approximation method.
