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 Δ_f H°(298.15 K, cd, Al₂OC) = ?625.6 kJ/mol.
