It was found that the data for 950 to 1150C could be described by:

D (cm2/s) = 6.8 x 10-2 exp[-15.9(kcal/mol)/RT]

The best linear fits to the solute diffusion data ([473] to [487], [517] to [528]) yield:

Ag: Ln[Do] = 0.33E – 15.5 (R2 = 0.73); O: Ln[Do] = 0.69E – 13.2 (R2 = 0.998);

O(l): Ln[Do] = 0.42E – 9.4 (R2 = 0.98)
