Thermodynamic properties of binary liquid alloys of silver with rare earth metals

Thermochemistry of some binary alloys of silver with the lanthanide metals by high temperature direct synthesis calorimetry

“…3 show that the relative molar volumes, when plotted against the atomic number of the lanthanide element, are nearly constant for AgLA and Ag 2 LA or show a slight decrease for Ag 51 LA 14 and Ag 3 LA with the exception for the values for Eu and Yb. When we compare these patterns with our enthalpies of formation in Fig.…”

“…This is of the same order of magnitude as the standard enthalpy of formation for the solid AgGd compound measured by Fitzner and Kleppa [9] (−29.7 ± 5 kJ/mol of atoms). In the study of Ivanov and Lukashenko, the Gibbs, free energies of formation for the liquid alloys have been calculated from mass spectrometric measurements at 1363 K [14]. Their value for AgTb at the 50/50 composition is given as −23.9 kJ/mol of atoms.…”

“…However, there are some measurements on liquid-iquid mixing of silver and lanthanide elements by Ivanov and Witusiewicz. who used isoperibolic calorimetry [13] and mass spectrometry [14]. We also found several studies of the Ag-LA systems, particularly of AgDy and AgHo, which all focused on measurements of the dissociation energies in the gas phase using mass spectrometry [15,16].…”

Experimental investigation and thermodynamic assessment of the Mg–Gd–Ag system focused on Mg-rich region

“…As Ag-Gd binary alloys are promising electronic materials and amorphous materials, the Ag-Gd system has been experimentally investigated repeatedly [25][26][27][28][29][30][31][32][33][34] and thermodynamic assessments have also been performed by various authors [35,36]. Besides the solution phases, the Ag-Gd system contains three intermetallic compounds AgGd, Ag 2 Gd and Ag 51 Gd 14 .…”
