“…The functions of integral entropy of the ternary system have positive values, which are close to the values of integral entropy of the Pb-Bi binary system [12][13][14] and are larger than that of the Pb-Sb binary system. 8,10 The entropy impact on the deviation from the ideal behavior decreases in a minor way as the Sb concentration in the alloy increases and reaches 40-50% at the extreme values of excess Gibbs energy. It has been previously shown that the entropy impact is 14% at x Pb = 0.18 molar fractions and is 39% at x Pb = 0.88 molar fractions at 773 K in the Pb-Bi alloys, 12 while in the Pb-Sb systems 10 the entropy impact is 46-48% in the wide Sb concertation interval.…”

Thermodynamic properties of the PbxSb0.25*(1-x)Bi0.75*(1-x), PbxSb0.5*(1-x)Bi0.5*(1-x), PbxSb0.75*(1-x)Bi0.25*(1-x) alloys of the Pb-Sb-Bi system, with the Pb concentration ranging from 3.0 to 87.0 mol. %, were studied by measuring the EMF equilibrium values in the temperature interval from 723 to 873 K in molten lead and potassium chlorides. The Pb-SbBi system activity, activity coefficients, partial and integral thermodynamic characteristics were calculated. The dependences of the excess integral thermodynamic functions are presented.

“…Использова-ние расплавов солей для переработки промпродуктов поможет достичь по-ставленных требований [1,2]. В литературе имеются данные о ис-следовании термодинамических харак-теристик двойных систем Pb-Sb [3] и Pb-Bi [4]. В этих работах методом э. д. с. измерены равновесные потенциалы двойных сплавов Pb-Sb и Pb-Bi в широ-ком диапазоне концентраций и темпера-тур в хлоридном расплаве.…”

The present work is devoted to the study of lead thermodynamic activity in the Pb-Sb-Bi alloys. The method for EMF measurements of the concentration cell: (–)Pb|KCl-PbCl2¦¦KCl-PbCl2|Pb-(Sb-Bi)(+) was used. The obtained concentration dependences of the galvanic cell EMF are described by linear equations. The lead activity in the ternary liquid-metal alloy demonstrates insignificant negative deviations from the behavior of ideal solutions.
