ELECTRON-TRANSFER IN THE CUCL-CUCL2-LICL MELT

A technique of measuring the electron transference numbers for the CuC l-CuCl2 ionic-electronic melt is developed. The ratio between the CuCl and CuCl2 mole fractions, the density, the electric conductivity, and the electron transference numbers are measured in the CuCl-CuCl2-LiCl molten salt system as a function of the temperature and the LiCl conc entration at p(Cl2) = 101 kPa. Effective mobilities and effective elec tron diffusion coefficients are calculated from the experimental data. Feasible mechanisms of electron transfer are contemplated.
