WebMar 20, 2024 · The pot lining in the Hall-Héroult cell is mainly composed of carbonaceous materials (carbon cathodes and side carbon blocks) and refractory materials (dry barrier materials and insulation bricks) (Xie et al., 2024). The lining structure becomes deformed or even broken by the penetration and corrosion of both high-temperature molten salt and ... WebPrevious current efficiency models of the rate of aluminium production in Hall-Heroult cells are briefly summarized. A description and discussion of the cathode processes are given, and rate limiting steps are evaluated under the assumption of no concentration gradients in the bulk electrolyte phase during electrolysis. An electrochemical current efficiency …
