Abstract: Partial pressure of oxygen and activity of manganese monooxide in the molten system Fe-Mn-Si-O (1)/CaO-MgO-MnO-FeO-Al₂O₃-SiO₂ (1) at the temperature of 1600°C was investigated using electrochemical methods. The dependence of the activity of MnO on its content in the mixture and on the optical basicity of the melt was determined. Dependence of the distribution coefficient of manganese on the partial pressure of oxygen and the optical basicity of the ionic melt was obtained.
