Activity Measurements of Solid Ni–In Alloys by EMF Method with Zirconia Solid Electrolyte

Prediction and thermodynamic analysis of In-activities of In–Ni alloys

“…2a and b show very satisfactory agreement between the majority of the experimental raw data from Ref. [3] and predicted values. (expressed as partial pressure of gaseous In) at specific mole fractions of indium (numbers beside symbols).…”

“…The same type of cell was used by Schmid et al [11] to obtain indium activities for liquid and solid alloys at temperatures between 1000 and 1350 K up to indium mole fractions of 0.65. New data on In-activities were reported recently by Katayama et al [3]. Emf measurements were performed using the galvanic cell (À) Kanthal, Re/In, In 2 O 3 jZrO 2 (þY 2 O 3 )j NieIn, In 2 O 3 /Re, Kanthal (þ).…”

“…Electrochemical measurements have been carried out for indium mole fractions between 0.05 and 0.55 and temperatures between 950 and 1170 K. An equation relating the quantity emf to In-activities is given by Ref. [3]. Using this relation in this work In-activities are calculated from the determined emf-values.…”

“…The aim of the present study is to compare new and recently reported data on indium activities of IneNi alloys [3] with predictions by previously developed Gibbs energy models for the indiumenickel system [1,2]. A comprehensive thermodynamic analysis is performed in order to investigate consistency of all experimental In-activity data accessible in the literature.…”
