| Abstract: | By use of radiotracer techniques, the iron self-diffusion coefficient in ferrous sulfide single crystals above 620 K was found to be D = Dδ exp {−[(81±4) + (84±20)δ]/RT} where the exponential units are kJ/mole, D is 1.7± 0.1×10 and 3.0±0.2 × 10 cm sec for diffusion in the a- and c-directions, respectively, and δ is the deviation from stoichiometry as given in the formula, FeS. This is a vacancy diffusion mechanism and is discussed in detail. Below 570 K the coefficient is lower than the values given by this equation because of vacancy ordering. The diffusion coefficient for sulfur is many orders of magnitude smaller than for iron. The significance of the data for the Fe−S reaction and other examples of iron diffusion is discussed.
