The diffusive behavior of 35S in single crystals was studied at 900 to 1000C. The results could be described by:

D (cm2/s) = 2.58 x 10-6 exp[-1.9(eV)/kT]

The best linear fits to the solute diffusion data ([5] to [25]) yield:

Ag: Ln[Do] = 0.44E – 11.0 (R2 = 0.93); Au: Ln[Do] = 0.43E – 15.2 (R2 = 0.82);

Cd: Ln[Do] = 0.47E – 23.8 (R2 = 0.94); Cu: Ln[Do] = 0.37E – 14.9 (R2 = 0.29)
