Abstract:

Results with galvanic cells of molten salts continued to be favorable. The CuCl-CuCl2 couple was found to afford a useful cathode for such anode couples as SnCl2-SnCl4, HgCl-HgCl2, and TeCl2-TeCl4. The CuCl-CuCl2 couple was found to approximate the potential of th SbCl3-SbCl5 couple. Research continued on the physical properties of molten salt mixtures and on the effects of component concentrations on the emf of galvanic cells. Thermal regeneration of anode materials centered on conversion of SnCl4 to SnCl2 and TeCl4 to TeCl2, with recovery of Cl2 in both cases. The former reaction occurred at 1700 K and the latter at 950 K. The relationship of current to chemical concentration and effect of circulation on cell current wer both established with cells of CuCl-CuCl2 cathodes and SnCl2-SnCl4 anodes. Current densities of 45 and 33 masq cm with and without circulation, respectively, were attained at E to the 12 power the densities were limited by the thickness of the electrolyte. Studies on solid electrolytes centered on PbCl2 and PbF2 and on the effect of adding KF, CsCl, and CdF2. Author
