An Electromotive Force Series in a Borosilicate Glass-Forming Melt

Abstract

An electromotive force series for redox couples was defined as a function of oxygen fugacity in a borosilicate melt at 1150°C. The resulting order of relative reduction potentials can be used to estimate the amounts of redox species in glass during processing. The electromotive force series in this melt is comparable to those in other silicate glassforming melts and in aqueous systems but differs in detail because of interaction of the solvents with individual redox couples.
