Thermodynamic properties of liquid silver–indium–antimony alloys determined from e.m.f. measurements

Abstract

Abstract The thermodynamic properties of liquid Ag–Sb –In alloys were determined using solid oxide galvanic cells with zirconia electrolyte. The following galvanic cells were employed: in the temperature range from 973 to 1200 K. (I) R e + kanthal, A g x − I n y − S b ( 1 − x − y ), I n 2 O 3 / / Z r O 2 + Y 2 O 3 / / N i O , N i , P t $$\begin{array}{l}\mathrm{Re}+\text { kanthal, } \mathrm{Ag}_{x}-\mathrm{In}_{y}-\mathrm{Sb}_{(1-x-y),} \\ \mathrm{In}_{2} \mathrm{O}_{3} / / \mathrm{ZrO}_{2}+\left(\mathrm{Y}_{2} \mathrm{O}_{3}\right) / / \mathrm{NiO}, \mathrm{Ni}, \mathrm{Pt}\end{array}$$ Thermodynamic properties of the liquid phase were described by the Redlich – Kister –Muggianu formula and the phase relations in the ternary system were calculated. The results of the calculations were compared with experimental data available from different literature sources.
