Description
Summary:This work, carried out in cooperation with five laboratories, members of the French Research group TherMatHT (Thermodynamics of Materials at High temperature), reports a collective effort to describe the thermodynamic functions of the Delafossite phase CuCrO2 by experimental methods. Indeed, to the best of our knowledge, this phase is poorly described in the literature, since the heat capacity (Cp) is only available in a limited temperature range, close to TNeel = 24 K and below 150 K [1]. The other published data concern Gibbs energy of reaction (ΔrG°) obtained by solid oxide electrolyte electromotive force method (emf) between 950 and 1350 K [2,3].
