Abstract
Partial enthalpy of mixing of yttrium (ÎmixH¯Y) in the Ge-Y system was measured at 1770 K using a new high-temperature mixing calorimeter. Literature data on the enthalpies of mixing in the Ge-Y system and results of present examination were compared and discussed. Temperature dependence of ÎmixH¯Y was estimated based on comparative analysis of the enthalpies of mixing, and corresponding heat capacity change at alloy formation was evaluated. Polynomial equations approximating thermodynamic functions (ÎmixH¯Y, ÎmixH, ÎmixC¯p,Y, and ÎmixCp) versus yttrium mole fraction were determined. Some trends observed in the thermodynamic properties of the Ge-Y alloys were described.
