Thermodynamic Investigation of Solid and Liquid Au-Te Alloys

Thermodynamic reassessment of the Au–Te system

“…10. The calculated heat content of AuTe 2 compound agrees well with the experimental data [20]. It can be seen that the Neumann-Kopp rule is valid for the AuTe 2 compound.…”

“…1. The Au-Te phase diagram calculated from the present thermodynamic description in comparison with experimental measurements [10][11][12][13][14][15] and [18][19][20]. [3] in the 0.48-0.67 at.% Te.…”

“…They also measured the heat content of four Au-Te alloys in the solid and liquid from 298 K to T (400 K < T < 900 K) on heating (drop method) with the help of a high temperature Tian-Calvet calorimeter [19]. Anres et al [20] measured the heat content of solid and liquid AuTe 2 from 298 K to T (471 K < T < 1022 K) using the same method as Yassin et al They obtained the enthalpy of formation of AuTe 2 compound at 298 K (−3.0 kJ per mole of atoms) and the enthalpy of fusion (19.1 kJ per mole of atoms). The enthalpy of formation of AuTe 2 compound at 728 K is −2.5 kJ per mole of atoms and the enthalpy of fusion at 737 K is 18.6 kJ per mole of atoms, which were measured by direct reaction calorimetry [3].…”
