Abstract : Diffusion studies were made for Cr51 diffusion in single crystals of NiO and CoO and for Co60 and Cr51 in compacted NiO and CoO. An improved Gruzin method was used to analyze the data. Measurements were made at temperatures between 977C and 1243C at an oxygen partial pressure one atm. Due to chromium evaporation losses no equations were developed for single crystal diffusion. A discussion of the evaporation problem was given. The diffusion of the chromium in the compacted oxides did not fit the theoretical equations. The diffusion of cobalt followed the theoretical development. (Modified author abstract)
