Serial sectioning techniques were used to study the diffusion of 109Cd in pure or Cd-doped single crystals. In the case of pure AgCl at 80 to 280C, the results could be described by:

D (cm2/s) = 8.22 x 10-6 exp[-0.57(eV)/kT]

At 280 to 445C, the results could be described by:

D (cm2/s) = 4.26 x 100 exp[-1.20(eV)/kT]

The data for the entire temperature range could be described by:

D (cm2/s) = 51.21 exp[-1.34(eV)/kT] + 6.34 x 10-6 exp[-0.56(eV)/kT]

The best linear fit to the solute diffusion data ([348] to [365]) yields:

Mn: Ln[Do] = 0.87E – 22.7 (R2 = 0.99)
