The diffusive behavior of Li was studied at 300 to 400C. The results could be described by:

D (cm2/s) = 9.1 x 10-3 exp[-13.1(kcal/mol)/RT]

The best linear fits to the solute diffusion data ([93] to [120]) yield:

H: Ln[Do] = 0.89E – 33.6 (R2 = 0.92); Li: Ln[Do] = 1.06E – 18.8 (R2 = 0.95);

Sb: Ln[Do] = 0.30E – 14.5 (R2 = 0.63)
