Solubility experiments of Ca and C in Mn melts with different contents of third elements j at different temperatures were carried out in Mo‐wire‐heated furnace. With these data the first and second order activity interaction coefficients of j upon Ca and C, based on the same activity and the same concentration method and also In γ Ca 0 and In γ C 0 , were evaluated. The solubility of Ca and C in liquid Mn formulated in relation to temperature was determined and the standard free energy of solution of Ca and C in liquid Mn based on 1 wt.% solution standard was evaluated, respectively.
