Reindarstellung von Neodym-Magnesium-Doppelnitrat durch fraktionierte Kristallisation
Preparation of pure neodym magnesium nitrate by fractional crystallisation (Short commun.)
Neodym magnesium nitrates from former separations containing 26 kgRE2O3 were fractionally crystallized (the more impure parts were submitted to a pre-concentration); after 117 rows there resulted neodym double nitrate containing 4.56 kg oxide of approximately 99.9% purity. The effective separation factors are discussed.
