Аннотация
The behavior of carbon–graphite subjected to treatment in the lithium carbonate Li2CO3 melt without cryolite and alkali-metal fluorides is studied to reliably estimate the influence of lithium on the surface layers of a carbon-containing cathode lining. The chemical composition and the structure of the carbon–graphite material after its interaction with lithium in the Li2CO3 melt have been studied. The high-temperature interaction of the system components in the melt is found to be accompanied by fracture of the operating surface of the carbon–graphite material, while the carbon–graphite surface does not failed upon interacting with lithium vapors. Based on the obtained data, a model for the formation of lithium ions during the reduction of lithium and its interaction with a carbon–graphite sample during the electrolysis of lithium carbonate is proposed.
