The diffusive behavior of 95Nb was studied at 878 to 2395C. The results could be described by:

D (cm2/s) = 1.1 x 100 exp[-96.0(kcal/mol)/RT]

The best linear fits to the solute diffusion data ([1015] to [1019], [1021] to [1030]) yield:

H: Ln[Do] = 0.55E – 9.4 (R2 = 0.92); N: Ln[Do] = 0.23E – 12.2 (R2 = 0.73);

Nb: Ln[Do] = 0.20E – 19.4 (R2 = 0.94)
