It was found that the data for 1150 to 1400C, could be described by:

D (cm2/s) = 6.92 x 100 exp[-77.6(kcal/mol)/RT]

The best linear fits to the solute diffusion data ([783] to [785], [793] to [796], [822] to [825], [830] to [832], [835] to [844], [848] to [855]) yield:

C: Ln[Do] = 1.23E – 28.8 (R2 = 0.995); Cu: Ln[Do] = 0.36E – 15 (R2 = 0.64);

H(l): Ln[Do] = 0.45E – 7.5 (R2 = 0.97); N: Ln[Do] = 0.20E – 8.3 (R2 = 0.97);

Ni: Ln[Do] = 0.58E – 37.4 (R2 = 0.24); O: Ln[Do] = 0.29E – 12 (R2 = 0.96);

S: Ln[Do] = 0.40E – 19.6 (R2 = 0.76)
