Abstract

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