• The diffusion coefficient of sulfur in liquid iron has been measured at the temperature range from 1, 560°to 1, 670℃. Since the concentration of sulfur was low in the present investigation, the diffusion coefficient was calculated by assuming as constants independent of the concentration. The result was expressed as follows : D=4.9×10^<-4>exp(-4350/T). The diffusion coefficient and the activation energy are nearly the same as those of carbon, cobalt and phosphorus in liquid iron. The activation energy is about one-tenth of the heat of vaporization and this shows that the holes in liquid iron are small. The theoretical values derived from the absolute reaction rate theory and the diffusion coefficient calculated by the Stokes-Einstein equation are compared with the experimental results.
