Abstract The liquid boundary of the slags of Ce_2O_3-CaO-CaF_2 system and the iso-activity lines for Ce_2O_3 and CeO_2 are given from experimental determination of the activity of Ce_2O_3 by equilibrating the slag with Sn in a graphite crucible under an atmosphere of CO at 1600℃. The activity of Ce_2O_3 in the slags containing certain CeO_2 or CaO, increases with the increase of concentration of CaO or CeO_2 respectively. The transition of CeO_2 to Ce_2O_3 under the condition of high temperature and low oxygen partial pressure was also discussed by thermodynamical analysis.
