Emf measurements are reported at 350C for cells with a Pyrex membrane and containing binary nitrate melts of the type MNO3 - AgNO3. The ion exchange model fits the data whereas the liquid junction model does not. Selectivity constants have the same order in the two systems as well as in aqueous solution. The significance of this is discussed. This work is part of the program to determine the mechanism of decomposition of chloride-catalysed ammonium nitrate melts. Understanding is required of Pyrex membrane potentials in order to develop a reference electrode for in situ acidity measurements in fused salts. Author
