Thermochemistry of binary alloys of transition metals: The Me-Sc, Me-Y, and Me-La (Me = Ag,Au) systems

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

“…1, we plotted our experimental enthalpies of formation for the molecular compositions which we studied (1:1, 2:1 and 3:1). The earlier values for some compounds of the lanthanide elements with Ag were measured by Fitzner and coworkers [4][5][6][7][8][9]. We see that the enthalpies of formation of the compounds of the Ag-LA composition show an increase in magnitude with increasing atomic number of the lanthanide element.…”

“…Several investigations of the alloys of gold and silver with transition metals and with some of the lanthanide elements were reported by Fitzner and coworkers [4][5][6][7][8][9]. Recently, we reported on our own study of alloys of the noble metals with transition metals and of alloys of gold with the lanthanide metals [10,11].…”

“…The alloys of the 2:1 composition were not studied previously in this laboratory by Fitzner and coworkers [4][5][6][7][8][9]. From La to Gd these phases melt peritectically, and from Tb to Er they melt congruently.…”

“…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]. Several investigations of the alloys of gold and silver with transition metals and with some of the lanthanide elements were reported by Fitzner and coworkers [4][5][6][7][8][9].…”

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

“…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].…”
