摘要：
The tendency of nickel to dissolve in iron silicate slags, both limefree and containing lime, was examined at 1573K, mainly in the range 0 - 4% nickel, by containing these slags in Ni - Fe crucibles and establishing equilibrium with Ni - Fe foils and CO//2 - CO gas - the latter controlled the oxygen potential. Activity coefficients were calculated for both nickel oxide and ferrous oxide in slag, and an equation was used to describe nickel solubility in terms of a nickel oxide and nickel metal component.
