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

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

“…2, we plot the enthalpies of formation of the 2:1 compounds for the Cu, Ag and Au alloys against the atomic number of the lanthanide elements. We cite previous measurements from this laboratory by Watanabe and Kleppa [3], by Fitzner and Kleppa [7][8][9], and recent work by the present authors [11,12]. These patterns are quite different from one another.…”

“…We report no new data for Cu compounds of this molecular composition, because we found that our products were not completely reacted. For some of the Ag and Au compounds, we are citing measurements by Fitzner and Kleppa [7,8] and new data by the present authors [11,12]. As the graphs show, all three patterns are quite similar.…”

“…Several investigations of the alloys of gold, silver and copper with transition metals and with some of the lanthanide elements were reported by Fitzner and Kleppa [7][8][9]. Recently, we reported our own study of alloys of the noble metals with transition metals and of the alloys of gold and silver with the lanthanide elements [10][11][12].…”

“…Over a period of a number of years a systematic study of the thermochemistry of the alloys of the noble metals with transition metals and with the lanthanide elements has been pursued in this laboratory [1][2][3][4][5][6][7][8][9][10][11][12]. Several investigations of the alloys of gold, silver and copper with transition metals and with some of the lanthanide elements were reported by Fitzner and Kleppa [7][8][9].…”

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 .…”
