Al–O equilibria in molten Fe–Al alloys were experimentally investigated. Molten steel with varying Al content (0.01–10 mass%) was equilibrated with a pure Al2O3(s) crucible at 1873 K in an Ar atmosphere with 3 vol% H2. The oxygen content of steel with Al content higher than 1.0 mass% was found to be much lower than that found in previous works, while the oxygen content for Al content less than 1 mass% was found to be slightly higher, resulting in a smaller equilibrium constant. The interaction parameters as well as the equilibrium constant of the Al–O equilibria in molten steel at 1873 K were reevaluated in the present study. The equilibrium for the Al deoxidation of molten steel was well represented up to 10.0 mass% Al using the reevaluated parameters.
