Bulk diffusion in single crystals was studied at 827 to 1192K. The diffusion coefficients were found to range from 1.2 x 10-18 to 1.1 x 10-11cm2/s. The results could be described by:
D (cm2/s) = 1.8 x 104 exp[-83.3(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)
