抄録

The isothermal phase relations for the CaO-AlO1.5-CeO1.5 system have been investigated at 1 773 K by a chemical equilibration technique. Activity of AlO1.5 in this system was also measured by equilibrating molten Cu and the CaO-AlO-1.5-CeO1.5 flux under a controlled oxygen partial pressure. The activity coefficient of Al at infinite dilution in molten Cu was determined at 1 773 K. Iso-activity curves of AlO1.5 for the CaO-AlO1.5-CeO1.5 system are drawn from the experimental results. The addition of CeO1.5 to the CaO-AlO1.5 system was found to decrease the activity coefficient of AlO1.5 in the melts. The effect of Ce addition to Al-killed steel was also discussed using the present results.
