Experimental and Theoretical Study of the Ag-Sn-Te Phase Diagram

Experimental and theoretical study of the Ag- Sn-Te system was carried out in the scope of the study. The isothermal sections at 350 and 500 °C were studied experimentally. The results were used together with other experimental data from the literature for the theoretical assessment of the system by the CALPHAD method. Generally, a very good agreement was obtained both for the phase diagram and for the enthalpies of mixing in the liquid phase. The existence of the ternary phase (Ag x Sn 2-x Te 2 ) was confirmed, and a slightly different composition ( x = 0.8) was evaluated in the experimental part of the study.
