Свойства фторида кальция как твердого электролита гальванического элемента

Abstract

Analysis of the limits of CaF2 applicability as a solid electrolyte for galvanic cells had been performed. Electron transport parameter of CaF2 under different fluorine activity was calculated from results of measurements of electric conductivity and e.m.f. of electrochemical cells with CaF2 solid electrolyte Similar calculations were performed for CaF2 saturated with oxygen. Obtained data was used for comparative analysis of the extremal values of Gibbs energy of oxides formation which may be determined correctly by measuring e.m.f. of galvanic cells with CaF2-based solid electrolytes.
