Abstract

It was shown that the published data on the thermodynamic properties of aluminum monooxycarbide Al2OC (ed) are not consistent with the phase diagram of the Al2O3-Al4C3 system. A thermodynamic modeling of the equilibrium state of the Al2O3-Al4C3 system made it possible to obtain new estimates of the standard entropy and enthalpy of formation of aluminum monooxycarbide: S°(298.15 K, cd. Al2OC) = 45.3 J/(K mol) and Δf H°(298.15 K, cd, Al2OC) = −625.6 kJ/mol.
