The ternary phase diagram Ag-Se-Sn was re-investigated experimentally. The current study was designed to contribute to a better understanding of phase equilibria in isothermal sections at 250, 400 and 550 degrees C using long-term annealed samples. An intermediate liquid region was observed at 550 degrees C in agreement with older published vertical sections of the ternary phase diagram Ag-Se-Sn. A huge homogeneity range in ternary intermetallic phase Ag8Se6Sn at 250 degrees C was determined by SEM/EDX analysis of long term annealed samples and confirmed by XRD measurements. A second ternary phase AgSe2Sn was observed at each of the studied temperatures. Complete isothermal sections at 250, 400 and 550 degrees C were constructed in the scope of this paper.
