Abstract:

The research was undertaken to study the electrolytelike behavior of impurity ions in solid solution. The diffusion of radioactive tracers in single crystals was studied by a microtome sectioning technique. The diffusion profiles for Pb, Cd, and Ce in KCl were obtained by measuring the activity in each section removed from the crystal. These data were analyzed by application of the Stasiw-Lidiard association Theory. Pb and Cd were found to agree well with the behavior predicted by the theory. Ce did not show the expected concentration dependence. To agree with the present theoretical model Ce must be completely associated with a vacancy over the temperature range studied. The measured parameters of these impurity ions are DPb 0.11 exp-27,100 calRT sq. cmsec DCd 0.0000468 exp-12,400 calRT sq. cmsec DCe 0.00112 exp-23,700 calRT sq. cmsec. Author
