Abstract

The Al-O equilibrium at high Al content during Al deoxidation process at 1873 K is reassessed in the present study due to the fact that there are still obvious discrepancies among the existing studies. The Fe-Al-O melts with varying Al content (0.01<[pct Al]<15) were equilibrated with pure solid Al2O3 at 1873 K in Al2O3 crucible under Ar (90 pct)-H2 (10 pct) mixture atmosphere, and a flux composed of CaO (30 wt pct)-Al2O3 (65 wt pct)-CaF2 (5 wt pct) was adopted to remove the inclusions to accurately measure the dissolved oxygen content in the samples. Then, based on experimental data, the interaction parameters between O and Al, as well as the equilibrium constant K, were deduced by WIPF (Wagner’s Interaction Parameter Formalism), UIP (Unified Interaction Parameter) formulism and the R–K polynomial (Redlich-Kister type polynomial), respectively. Further, the applicability concentration range of the WIPF in Fe-Al-O melts was investigated. It was found that the WIPF can be used when the concentration range of Al content is less than 9 wt pct, while the adoption of WIPF will certainly lead to a large deviation at higher Al content. Besides, when the Al content is smaller than about 2 wt pct, the WIPF can be used without considering the second-order interaction parameters between Al and O. However, the second-order interaction parameter must be introduced at a higher Al content range. Finally, the activity and activity coefficient of Al and O in Fe-Al-O melts was calculated using R–K polynomial. The results show that with the increase of Al content, the activity and activity coefficient of O decreases, while activity and activity coefficient of Al obviously increase.
