Abstract
Calcium fluoride has been conventionally used as a solid electrolyte to measure fluorine chemical potentials in high temperature systems. However in this investigation, this electrolyte has been used as a sulfur sensor. Open-circuit emf measurements have been carried out with the following four galvanic cells The cells were investigated in the temperature range, 500°-900°C. Using Richardson and Antill's data for the standard Gibbs energy of formation of Cu2S, the standard Gibbs energies of formation of FeS, Ag2S, MnS, and CrS have been determined.
