The phosphorus partition between BaO-BaF2 fluxes and Fe-Cr-Csatd. alloys was measured at temperatures ranging from 1 175°C to 1 300°C under a CO atmosphere.<BR>The phosphorus partition ratio increases with increasing BaO content in the fluxes and decreases with increasing chromium content in Fe-Cr-Csatd. alloys. The BaO-BaF2 system was found to have a large phosphate capacity ranging from 1026 to 1028.5 at 1300°C, which is much larger than that for the CaO-CaF2 system. The enthalpy change for the dephosphorization reaction by BaO bearing fluxes was determined to be-528 kJ/mol. The chromium partition ratio increases with an increase in BaO content especially in the higher BaO content range. The possibility of the removal of phosphorus from Fe-16% Cr-C alloys without much oxidation loss of chromium by using 50% BaO-50% BaF2 flux was demonstrated.<BR>Furthermore, the activity of BaO for the BaO-BaF2 system was determined at 1 200°C and 1 300°C and the activity of BaF2 was calculated by using the Gibbs-Duhem relationship. The phase diagram for the BaO-BaF2 system was also discussed.
