Enthalpies of mixing of the liquid phase in the ternary system Ag–Au–Bi

Phase equilibria in the Ag–Au–Bi ternary system

“…As mentioned in a previous paper [6], the bordering systems Ag-Au, Ag-Bi and Au-Bi are well known. On the other hand, no experimental study is available on the ternary Ag-Au-Bi system.…”

“…The investigation of the system Ag-Au-Sb is still in progress and results have been the goal of the XXXIth JEEP communication [5]. So, the present paper only concerns the results obtained on the Ag-Au-Bi ternary phase diagram at equilibrium.…”

“…To our best knowledge, no study has been published on the Ag-Au-Bi ternary system, except the measurements of the heat of mixing of the liquid phase [6].…”

Verification of Phase Diagrams by Three-Dimension Computer Models

“…Ag-Au-Bi: Despite the fact that the information, placed into the atlas, was thoroughly checked (according to its authors), the description of the Ag-Au-Bi system is contradictory: in the binary system Au-Bi, cited according to the data [14][15][16][17][18][19], the compound Au 2 Bi decomposes at the temperature 110°C, whereas the solid solution on its basis in the ternary system isopleths exists also at 0°C (Figures 4c and 4d). To understand these contradictions, it is necessary to discuss the papers [14][15][16][17][18], the information from which in the form of an isothermal section and four isopleths were included into the atlas.…”

“…To understand these contradictions, it is necessary to discuss the papers [14][15][16][17][18], the information from which in the form of an isothermal section and four isopleths were included into the atlas. The Ag-AuBi=A-B-C T-x-y diagram has a simple geometric construction.…”
