Standard Enthalpy of Formation of CuAl2O4 Revisited

2015 
Due to discrepancy in the standard enthalpy of formation, ΔH_f^0, of copper(II) aluminate (CuAl2O4) reported in thermodynamic databases, the calculated reaction enthalpy, ΔH_r, of CuAl2O4 with reducing gases varies considerably. In this work, the standard enthalpy of formation, ΔH_f^0, of copper(II) aluminate (CuAl2O4) is reassessed using the reaction enthalpy, ΔH_r, of CuAl2O4 with CO measured by differential scanning calorimetry (DSC). A value of –1824.4±4.1 kJ/mol was found for the standard enthalpy of formation, ΔH_f^0, of CuAl2O4.
