چکیده انگلیسی
The enthalpy increments of the Zr0.50Au0.50 phase have been measured by high-temperature drop calorimetry in the temperature range 372–1245 K. From these results, heat capacities of ZrAu have been derived and two changes of the Cp values have been observed, in agreement with the existence of three crystalline forms of ZrAu. No latent heat was observed for the low-temperature (564 K) transition, whereas the enthalpy change at high temperature (841 K) was estimated at 1.55 kJ·mol−1, from enthalpy increments obtained by drop calorimetry. These results are discussed in relation to the crystal modifications already reported for the ZrAu compound.
