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 cal/RT) sq. cm/sec; DCd = 0.0000468 exp(-12,400 cal/RT) sq. cm/sec; DCe = 0.00112 exp(-23,700 cal/RT) sq. cm/sec. (Author)
