The relation berween cerium and oxygen in liquid iron together with the phase of deoxidation products at 1650℃ was studied. The following results were obtained : 1) The composition of deoxidation products is considered to be that the O/Ce ratio is 1.5 to 1.64 ([%Ce]<10 ppm), 2) If the deoxidation products are assumed as Ce_2O_3,the deoxidation equilibrium constant can be expressed as below, Ce_2O_3=2 Ce__-+3 O__- K=4.0×10^<-15>, 1650℃, [%Ce]<10 ppm.
