Phase diagrams of the Ag-In-Zn ternary system

There are 6 single phase regions, 9 two-phase regions, and 4 ternary tie-triangles in the isothermal section of Ag-In-Zn system at 500°C. The 6 single phase regions are Ag, β-AgZn, γ-Ag₅Zn₈, and ε-AgZn₃, liquid, and ς-Ag₃In. The calculated results using preliminary models based on the thermodynamic models of its three constituent binary systems are qualitatively in agreement with the experimental measurements. However, the significant ternary solubilities of the binary compounds, especially in the β-AgZn phase, need to be taken into considerations, so that quantitative correct modeling can be achieved.
