“…Louadi et al [14] used drop calorimetry to measure the enthalpy increment of the eutectic Cu-Te alloy (71 at % Te) in the range 512-800 K. According to x-ray diffraction data, the alloy consisted of CuTe and Te. Using the data reported in [1,9,14], we estimated the average enthalpy of formation of the solid eutectic alloy at 298 K and obtained -6.4 kJ/mol.…”

“…Using the data reported in [1,9,14], we estimated the average enthalpy of formation of the solid eutectic alloy at 298 K and obtained -6.4 kJ/mol. This result agrees to within measurement accuracy with the value calculated by the additivity rule from the ∆ f H 0 (298 K) of solid CuTe (Table 2) and tellurium, which points to good reliability of the ∆ f H 0 (298 K) data extracted from the emf measurements by Abbasov et al [12].…”

The reported standard functions of formation of copper tellurides are critically evaluated and optimized. The thermodynamic data obtained for hitherto unexplored phases shed some light on the origin of discrepancies between the T -x phase diagrams of the Cu-Te system reported by different groups. Fig. 3. Composition dependences of heat capacity in the Cu-Te system at (1) 298 and (2) 400 K; the open data points represent our estimates for Cu 13 Te 7 , Cu 9 + x Te 5 , Cu 7 Te 4 , and Cu 3 -x Te 2 (phases 2-5 in Fig. 2) by the NeumannKopp rule, and the filled data points represent experimental heat capacity data for Te, CuTe, Cu 2 Te, and Cu.
