Ie. Soboleva et al., THE INFLUENCE OF MIXED-LIGAND COMPLEX-FORMATION ON THE SEPARATION OF VOLATILE NEODYMIUM AND CALCIUM DIPIVALOYLMETHANATES BY VACUUM SUBLIMATION, Journal of alloys and compounds, 225(1-2), 1995, pp. 390-392
Performance evaluation of neodymium and calcium separation by vacuum s
ublimation in the form of dipivaloylmethanates as well as in condition
s when two types of ligands, dipivaloylmethane (HDpm) and pivalic acid
(HPiv), are present was made. It was found that the addition of HPiv
to the mixture NdDpm(3)+CaDpm(2) caused an increase in the separation
efficiency, and the production of pure NdDpm(3) in the sublimate.
