Abstract
The influence of chromium on self-diffusion of cations in metal-deficit man-ganous sulphide, Mn1_yS, has been studied as a function of temperature and sulphur activity, using radio-tracer technique. It has been found that the rate of Mn self-diffusion in chromium doped Mn1_yS is higher than that in pure manganous sulphide and does not depend on equilibrium sulphur pressure. In addition, the activation energy of self-diffusion in Mn1_yS-Cr2S3 solid solution is lower than that in pure Mn1_yS. Both these results are in agreement with theoretical predictions based on simple defect model in Mn1_yS, assuming that the predominant defects in this sulphide are non-interacting, doubly ionized cation vacancies and electron holes.
