WebAbstract. Electrode reactions are complex in Hall-Héroult cells. At the cathode, aluminum is extracted leaving behind a melt at the interface which is richer in sodium fluoride and has a higher liquidus temperature. The anode reaction produces CO 2 whereas CO is thermodynamically favored. These kinetically controlled factors result in about ... WebApr 3, 2024 · Easy. Moderate. Difficult. Very difficult.
