Summary

The solubilities of Fe, Cr and Ni have been measured in liquid Na. Iron is more soluble than Ni and Cr in Na at T>600°, yet Ni and Cr are selectively leached from stainless steels during corrosion. Concentrations of Fe and Cr in circuit Na (low oxygen) generally approximate their solubilities at Tmax, whereas concentrations of Ni are generally less than its solubility at Tmax. The location of Ni and Cr deposits as described by Roy et al. and by Bogers was shown to be consistent with the temperature dependence of the Ni and Cr solubilities.
