测定了金属钕在NdCl_3-MCl_n体系、NdCl_3-(90.0wt％KCl,10.0wt％MCl_n)(M=Li、Na,K、Ca、Sr、Ba;n=1或2)截面和NdCl_3-LiF体系(富NdCl_3区)中的溶解损失。发现钕在NdCl_3-KCl、NdCl_3-CaCl_2和NdCl_3-(90.0wt％KCl,10.0wt％CaCl_2)体系中溶解损失较小,而在NdCl_3-KCl体系中随温度的升高而加大。当体系中NdCl_3浓度<50wt％时,钕在混合盐中的溶解损失低于在纯NdCl_3中的1/3。NdCl_3中加入LiF能减小钕的溶解损失。同时探讨了金属钕及其盐相互作用的本质。
The effects of Nd on NdCl_3-MCl_n system, NdCl_3- (90.0wt% KCl, 10.0wt% MCl_n) (M = Li, Na, K, Ca, Sr, Ba; n = 1 or 2) (NdCl_3 rich region) in the dissolution loss. It is found that neodymium has less dissolution loss in the system of NdCl_3-KCl, NdCl_3-CaCl_2 and NdCl_3- (90.0wt% KCl, 10.0wt% CaCl_2) and increases with temperature in NdCl_3-KCl system. When the concentration of NdCl_3 in the system is less than 50wt%, the dissolution loss of neodymium in mixed salt is lower than that in pure NdCl_3. Addition of LiF to NdCl_3 can reduce the dissolution loss of neodymium. The nature of the interaction between neodymium and its salts was also discussed.
