Abstract

The equilibrium between a copper-nickel alloy and an oxide melt in the Cu2O-NiO-SiO2 system was studied experimentally. The distribution coefficients of nickel were determined as a function of the content of silicon dioxide, and the ratio of activity coefficients of nickel and copper oxides at 1300°C was found.
