The permeabilities of oxygen through the molten Fe_2O_3-CaO-SiO_2-Al_2O_3 and CaF_2-CaO-SiO_2-Al_2O_3 systems were measured by means of an experimental procedure which was developed by the authors. Those trough the Fe_2O_3-CaO-SiO_2-Al_2O_3 and CaF_2-CaO-SiO_2-Al_2O_3 melts were found to be in the range of 1×10^<-8> to 1×10^<-6> and 5×10^<-12> to 5×10^<-8> moles O_2/cm・s, respectively. The permeability was raised by a factor of 10 to the 10th power when 0.2wt% of Fe_2O_3 was added to 40wt% CaO-40wt%SiO_2-20wt% Al_2O_3 melt. The permeabilities through the molten slags with Fe_2O_3 are proportional to the 1/4th power of oxygen partial pressure in the atmosphere. The permeabilities through the molten slags without Fe_2O_3 are directly proportional to the oxygen partial pressure in the atmosphere. They increase when CaF_2 is added to the Fe_2O_3-CaO-SiO_2-Al_2O_3 melt.
