WebbKeywords: Inert anode, inert cathode, specific energy consumption in aluminium reduction cells, cell retrofit, Hall-Héroult process. 1. Introduction Since the early days of aluminium smelting, the dream of operating a Hall-Héroult cell producing oxygen as a by-product rather than carbon dioxide has been pursued. The fundamental difference
Why do they use graphite electrodes in the Hall–Héroult process?
WebbThe cathode is the part to be plated. At the anode, the metal is dissolved and then transported to the cathode. If the metal is insoluble in the plating solution, a soluble compound in solution constitutes the electrolyte, such as copper sulphate. Dissolved in an aqueous medium, CuSO4 ·5H 2 O ionizes.
