Abstract

Emf of galvanic cells with zirconia solid electrolyte was measured to determine the activity of indium in the liquid In-Sb-Ag and In-Sb-Te systems in temperature ranges from 970 to 1280 K for the In-Sb-Ag system and for the In-Sb-Te from 870 to 1260 K. The following cells were used: Pt/Ni, NiO|ZrO2 (+ CaO) | In-Sb-Ag, In2O3/Re/Pt, Pt/Ni, NiO | ZrO2 (+ CaO) | In-Sb-Te, In2O3/Re/Pt. The isoactivity curves in the liquid In-Sb-Ag and In-Sb-Te systems at 1100 K were derived from combining the activity data of the In-Sb, In-Ag and In-Te binary alloys. The shape of isoactivity curves in the liquid In-Sb-Ag exhibits a slight bend to the Sb-Ag binary side, and those of the liquid In-Sb-Te gather from the whole composition range of the In-Sb binary alloy to the intermediate composition of the In-Te system.
