N2 - This study reportsAluminum the directAlloys production of aluminum–manganese alloysAluminum–manganese alloys during the electrodeposition of aluminumAluminum in cryolitic melts. For the purpose of measuring current efficiencyCurrent efficiency, experiments were conducted in a laboratory cellCell. The temperature was changed between 960 and 980 °C at a cryolite ratio (CR) of 2.2 and a cathodic current density (CCD) of 0.9 A/cm2. Up to 3.0 weight percent of manganese was present. Mn2O3 was used as a methodMethod of manganese addition. To track the dissolutionDissolution of manganese during electrolysisElectrolysis, bath samples were routinely taken, and ICP-MS was examined. Al-Mn alloyAlloys electrodeposition current efficiencyCurrent efficiency was estimated to be in the region of above 90%. Estimates of aluminumAluminum's current efficiencyCurrent efficiency were made. The metal deposits’Deposits' hardened surfacesSurface were essentially flat, but some were deformed.
