Abstract

Equilibria between a copper-nickel alloy and oxide melt of the binary system Cu2O-NiO were studied and the activity coefficients of copper and nickel oxides at 1573 K in the homogeneity region of the oxide melt (up to 11.6 mol % NiO) were determined. Similar values were also found by calculation from the phase diagram of Cu2O-NiO.
