Abstract

The influence of CaF₂ on the thermodynamic behavior of carbon in the CaO-Al₂O₃-CaF₂ slag at 1773 K was investigated on the basis of carbide capacity concept. The carbide capacity increases with increasing CaF₂ content up to about 25mol%, followed by nearly constant value in the CaO_satd-Al₂O ₃-CaF₂ system. The capacity in the CaO-Al ₂O₃-CaF₂ (44-49 mol% CaO) system rapidly increases by increasing the X_CaF2/X_Al2O3 ratio up to about unity, and then the capacity-increasing rate decreases at X_CaF2/ X_Al2O3≥1. The carbide capacity increases with an increase of CaO/Al₂O₃ ratio at a fixed CaF₂ content; also, the addition of CaF₂ greater than about 14mol% would have no effect on capacity regardless of CaO/Al₂O₃ ratio. The iso-carbide capacities obtained in the present work are very similar to the iso-sulfide capacities available in the literature.
