用化学平衡法研究了1200℃铜液中Ce-S和Y-S的反应平衡。求得Ce和Y的脱硫常数、脱硫产物CeS与YS的标准生成目由能、溶质间活度相互作用系数,Ce和Y在铜液中的标准溶解自由能及其活度系数。
The thermodynamic properties of Cu-Ce-S and Cu-Y-S liquid solutions werestudied by the chemical equilibrium technique at 1200℃. The equilibrium constants and thestandard free energies of CeS or YS formation were determined for the reactions CeS=[Ce]+[S]and YS=[Y]+[S]. For the solutions of Ce_((1)) and Y_((1)), in pure Cu according to the reactions:Ce_((1))=[Ce], and Y_((1))=[Y], the standard free energies of solutions were found. The first orderand second order interaction coefficients between solute elements as well as the activity coeffi-ciants γ_C~0 and γ_Y~0 in liquid Cu were also determined.
