Molten oxide electrolysis (MOE) is presented as a promising carbon-free electrochemical technique for decomposing metal oxides directly into liquid metals and oxygen gases. This study investigates the efficacy of an iridium anode, key for sustainable oxygen evolution, within ironmaking cells operating with varying electrolytic compositions. The primary objective is to evaluate how the basicity of the electrolyte influences the stability of the iridium anode during MOE. The methodology employs comparative analysis of iridium loss rates in acidic melts with high silica content versus basic melts with elevated calcia content. Results indicate that the iridium anode loses stability significantly faster in basic conditions, underscoring the substantial influence of electrolyte basicity on anode performance. These findings highlight critical considerations for the design and operation of MOE systems in the steel industry, aiming to develop environmentally sustainable metal production methods.
