摘要：
Performance evaluation of neodymium and calcium separation by vacuum sublimation in the form of dipivaloylmethanates as well as in conditions 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.
