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-Al2O3-MgO slags in an Al2O3, CaO or MgO crucible. The values for eOMg, rOMg, rOMg, O, eMgO, rMgO and rMgO, Mg were determined as -46, 800, 2400, -70, 1800 and 2400, respectively. Nitride capacities, C(N), defined by (mass%N)·PO23/4/PN21/2 were obtained by using the present results for nitrogen distribution ratio, LN {=(mass%N) / [mass%N]}, and the reported values for the activity of Al2O3.
