The O/sub 2/ and CO/sub 2/ mixtures which were noticed in the anode chamber during electrolytic decomposition of molten fluoride and chloride mixtures were ascribed to the discharge of ions containing O. Syatematic studies were undertaken to establish the source of the O-containing materials by carefully following the course of the electrolysis; using porcelain containers, a graphite anode, and a molten Pb cathode; while preparing Pb-alkali metal alloys. After 3 to 4 hours of electrolyzing the NaCl-KCl mixture at 700 tained it was found that the originally 100% Cl content of the anodic gas was reduced to 98%. These studies showed that the presence of the O/sub 2/ and CO/sub 2/ observed in the mixtures cam be explained by the fact that the alkali metals dissolved in the mixture reached the sunface where they are oxidized and where the O-containing compounds of Si are reduced by interaction of the dissolved metal with the container material. It was thus established that the dilution of Cl was not due to the inflow of sir due to lack of tightness. The electrolyte must be protected from contact with air and the container must be provided with a suitable liner. (TTT)
