| Abstract |
The activities of tin in liquid tin-antimony alloys were determined in the temperature range of 671 to 906K by means of the galvanic cell: Sn(l)｜Sn^(2+)(KCl-LiCl)｜Sn-Sb alloy(l). The entropies of formation of this alloy system were calculated from these results and the values of heat of formation measured by calorimetric methods. From the curvatures of the plot of activities and entropies versus the concentration of the alloys, it is suggested that the solid β phase has an influence on the thermodynamic properties of Sn-Sb molten alloys. |
