Abstract

The process of dissolution of titanium, silicon, and boron oxides in carbonate melts is studied. Voltammetric studies are used to show that the most electropositive electrochemical process in molten carbonates is discharge of carbon dioxide dissolved in the melt to elementary carbon. Electrochemical synthesis of carbides in carbonate melts is possible at the potentials more positive by their value than the potential of carbonate decomposition. Interaction of titanium and silicon carbides with carbonate solutions is studied.
