Thermodynamic properties of dilute Cu–Fe–Pb solutions

Influence of Ag on the activity of Zn in {(1−x1−x2)Sn+x1Zn+x2Ag}(l) atT=903 K

“…This method has been successfully applied for the alloys, with one volatile component. (2)(3)(4)(5) The studied mixture {(1 − x 1 − x 2 )Zn + x 1 Sn + x 2 Ag}(l) and the reference mixture {(1 − x)Sn + xZn}(l) were placed inside a closed crucible (2)(3)(4)(5) under a reduced pressure of argon and saturated with the vapour of zinc until equilibrium was reached. In the equilibrium state the activity of Zn is the same in all the mixtures inside the closed system.…”

Lead Activity in Ni–Pb–B and Ni–Pb–Cr Liquid Diluted Solutions

“…The relative method of equilibrium vacuum saturation, applied for the first time for activity determination of lead in Cu-Fe-Pb system (6) and described in details in the previous papers(5)(6) , has been used in this study. The method employed consists of saturation of the Ni-Pb-j and the reference solution, CuPb, with the lead vapour.…”

“…The distinct linear rameter values and the relative difference of ionic volumes di+n-j+pi has been found. The relative difference of ionic volumes in ternary solutions has been defined as follows: (6) where ri+n, rj+p-ionic radii of metals i and j, respectively; n,p-number of valence electrons of metal i and j, respectively. Another regularity has been observed as well (2).…”
