A study was made of the H absorption of liquid Fe which was held in ring-shaped tubes. The resultant data (table 63) could be described by:
D (cm2/s) = 5.21 x 10-2 exp[-4.42(kcal/mol)/RT]

Diffusivity of H in Molten Fe
Temperature (C) | D (cm2/s) |
1560 | 3.30 x 10-3 |
1600 | 3.51 x 10-3 |
1650 | 3.73 x 10-3 |
