• The diffusion coefficient of sulfur in liquid iron saturated with carbon has been measured in the temperature range from 1, 390°to 1, 560℃ by using radioactive sulfur S^<35>. It was found to be 2.9-3.6×10^<-5> cm^2/sec and its dependency on temperature was expressed as follows : D=2.8×10^<-4> exp (-3, 800/T) The values of the diffusion coeofficient are lower than those of the same concentration in iron-sulfur binary solution. The decrease of the diffusion coefficient by the presence of carbon can be explained partly as due to the fact that the decrease of activity coefficient of sulfur with concentration is larger than that in binary solution.
