“…However, the concentration change after electromigration particularly toward the anode is much larger in the Klemm method. One of the great advantages of this method in comparison with the one in aqueous solutions [7] is that countercurrent flow of cations occurs spontaneously owing to the gravity and the capillary action of the diaphragm. Therefore, in a binary mixture with a common anion, the less mobile cation is readily enriched at the anode side.…”

The Klemm method of isotopic enrichment (countercurrent electromigration of molten salts) and many of its implications are reviewed and discussed. On the basis of this principle, a small amount of 6 Li was enriched in some experiments from its original abundance, 7.6%, to 94.9% at about 300 • C. The variation of the conditions led to a modified setup where, by disposing a small amount of NaNO 3 between the catholyte ( NH 4 NO 3 ) and the zone of LiNO 3 , the frontal part, where 6 Li is to be enriched, could be kept stable under high current density for more than one month without any problem of corrosion. The reasons and implications of this new step are discussed, underlining the up-to-dateness of Klemm's experiment.
