Based on the reciprocal relationships with respect to the interaction parameters on mass percent, the first-order and second-order interaction parameters between Mg and O in liquid nickel were estimated at 1873 K in the equilibrium experiments between liquid nickel and CaO-Al<SUB>2</SUB>O<SUB>3</SUB>-MgO slags in an Al<SUB>2</SUB>O<SUB>3</SUB>, CaO or MgO crucible. The values for <I>e</I>OMg, <I>r</I>OMg, <I>r</I>OMg, O, <I>e</I>MgO, <I>r</I>MgO and <I>r</I>MgO, Mg were determined as -46, 800, 2400, -70, 1800 and 2400, respectively. Nitride capacities, <I>C</I><SUB>(N)</SUB>, defined by (mass%N)·<I>P</I>O23/4/<I>P</I>N21/2 were obtained by using the present results for nitrogen distribution ratio, <I>L</I><SUB>N</SUB> {=(mass%N) / [mass%N]}, and the reported values for the activity of Al<SUB>2</SUB>O<SUB>3</SUB>.
