摘要：

The activity of oxygen in liquid Sn from 800 to 900-degrees-C and in liquid BaxCu1-x(x = 0.25 and 0.35) at 900-degrees-C have been measured by a modified coulometric titration method on the galvanic cell: Q in liquid Sn or BaxCu1-x/yttria stabilized zirconia/Air, Pt. The standard Gibbs energy changes for the reaction 1/2 02 (1 atm) --> O (1 a m percent) in liquid Sn metal are determined to be DELTAG-degrees = -177,940 + 22 T (K) (+/-300) J/g-atom. DELTAG-degrees for BaxCu1-x liquid alloys at 900-degrees-C are -244,920 and -259,464 J/g-atom, respectively, for x = 0.25 and 0.35. The activity coefficients of the BaxCu1-x alloys are noted to deviate from the quasi-interstitial and quasi-substitutional solvation-shell models.
