Measurements on Galvanic Cells Involving Solid Electrolytes

Abstract

Electromotive force measurements on galvanic cells involving solid electro-lytes have been made in order to obtain the standard molar free energy of formation of CoO, NiO, Cu~O, AgeS, Ag~Se, PbS, and several phases of the system Ag-Te at elevated temperatures. Haber and Tolloczko (1), Katayama (2), Reinhold (3, 4), Treadwell, Ammann, and Zfirrer (5), Croatto and Bruno (6), Rose, Davis, and Ellingham (7), Sator (8), and others have shown that emf measurements on galvanic cells involving solid electrolytes may yield valuable thermodynamic data. The following investigations have been made in order to show new potentialities of emf measurements on galvanic cells involving solid electrolytes for the determination of the standard molar free energy of formation of oxides, sulfides, selenides, and tellurides at elevated temperatures.
