Abstract : The cathodic deposition of carbon from fused carbonates is reported. The yield is quantitative under favorable conditions (600 C, Ar atmosphere) but diminishes in the presence of CO2 and with rise in temperature. If the melt does not contain Li(+) ions, alkali metal is the only cathodic product. The distinctive feature of the electrolytic carbon is an enhanced electrochemical activity; thus the rest potential is 0.8V negative with respect to commercial carbons. A thermodynamic treatment correlates this activity with the occlusion of oxide ions in the highly porous carbon deposit. The marked solvent effect is shown to arise in the same way. (Author)
