Add time:08/01/2019    Source:sciencedirect.com

Low-temperature (5 to 350 K) heat capcity, fluorine combustion, and high-temperature (350 to 1500 K) drop-calorimetric measurements have been performed on a specimen of zirconium ditelluride ZrTe2. Thermodynamic quantities are reported at T = 298.15 K: the standard molar enthalpy of formation, ΔfHmo(T) = −(294.1 ± 6.7) kJ · mol−1; the standard molar heat capacity, Cp, mo(T) = (74.11 ± 0.37) J · K−1 · mol−1; the standard molar entropy, Smo(T) = (124.24 ± 0.63) J · K−1 · mol−1; and the standard molar Gibbs energy of formation, ΔfGmo(T) = −(290.0 ± 6.7) kJ · mol−1, all with po = 101325 Pa. The thermodynamic properties of ZrTe2 have been calculated to 1500 K.
