Experimental investigation and thermodynamic prediction of the Ag-Ge-Sb phase diagram

Identification of coexisting phases in the chosen as-cast samples and samples annealed at 400 °C was performed using SEM-EDS and XRD methods. Liquidus temperatures for selected samples with overall compositions along three vertical sections Ag-Ge0.5Sb0.5, Ge-Ag0.5Sb0.5 and Sb-Ge0.5Ag0.5 were measured by DTA. Ternary eutectic reaction was experimentally determined by means of applied experimental techniques.
