Most electrolytes used for production and refining of many metals are based on molten halides of the alkali metals. Their most important characteristic is the decomposition potential, from which the degree of participation of alkali cations in cathode processes can be estimated. Its direct experimental determination does not give reliable results because of the mutual solubility of alkali metals and their molten halides. The values calculated by various authors using the thermodynamic method differ considerably, especially in the case of bromides and iodides. Therefore they require verification and correction. The authors have therefore measured, as functions of temperature, the differences between the decomposition potentials of these melts in a cell without diffusional transference of ions from one compartment into the other: X/sub 2g/, C/sub s/absolute value of MX/sub Zeta/M-Pb/sub Zeta/absolute value of MCl/sub Zeta/C/sub x/, Cl/sub 2g/, where M = Li, Na, K, Rb, or Cs; X = Br or I.
