Aluminium-oxygen equilibria between CaO-Al=0, melts and liquid iron were studied in the temperature range of 1 823 to 1 923 K, using an alumina and lime crucibles. The equilibrium constant K for the reaction: 2Al+3Q=Al.O, was discussed with reference to the supersaturation for nucleation of alumina, and compared with the p~evious experimental andthermodynamicdata. The su persaturation was observed in the experiments in which an Fe-AI alloy with low concentrations of initial oxygen was used under the condition of no stirring.
