The performance of current sidewalls made of carbon and silicon-based materials relies on the existence of a frozen electrolyte layer. The development of Hall-Héroult cell technologies, such as inert anodes and wettable cathodes, calls for new sidewall materials as the frozen ledge may no longer be applicable. This study identifies nickel ferrite as a potential sidewall material, with an emphasis on its resistance to cryolite and air attack. The presentation outlines strategies to address the combined corrosive effects of cryolite, molten aluminum, and oxygen on sidewalls. A multi-layer approach is proposed to optimize both the chemical and heat flux requirements of sidewalls. Additionally, the study discusses critical issues related to joining materials, process control, manufacturing, maintenance, and cost that must be resolved before implementing new sidewall designs. Overall, this research highlights the necessity for innovative materials and methods in the production of aluminum through the Hall-Héroult process to enhance efficiency and performance.
