Title

Solution and interaction of oxygen in complex liquid silver alloys

Abstract
The improved coeassoc Sieverts technique has been employed to reinvestigate the influence of temperature on the solubility of oxygen in liquid Ag-Au alloys (0 to 60 wt pct Au). Its effect is found to be slightly more pronounced at higher additions of gold as compared to results of earlier investigations. In addition the influences of temperature and composition on oxygen solubilities in multi-component Ag-O-Au-Pt-Pd alloys (0 to 12 wt pct each) have been determined. The result is found predictable by means of the recently developed "equivalence method" based only upon the knowledge of known data in ternary Ag-O-j alloys. The results of this as well as earlier investigations are evaluated on a molal basis, yielding partial molal enthalpy and entropy of solution values. Thus the "equivalence method" recently applied to solubilities and activity-coefficients at a given temperature, is found applicable to partial molal energetic data as well. (IFAM)
