Review—Primary Production of Aluminium with Oxygen Evolving Anodes

Due to environmental and economic concerns, carbon-free aluminium production has been an ultimate goal for industries. For the past few decades, a considerable amount of research conducted find inert anode material that could replace consumable carbon anodes electrolysis. Anodic materials such as metals, ceramics cermets have studied extensively. All these their advantages disadvantages. However, metal alloys proven effective due resistance high-temperature corrosion ability produce protective oxide layer. successful adaptation metallic into electrolysis cell, electrolyte with low-operating temperature high alumina solubility good electrical conductivity is required. Another significant component cell wettable cathode reduce anode-cathode distance. This review discusses progress on anodes, cathodes electrolytes.
