A Study on the Dissolving Loss of Nd in the NdCl_3-Containing Systems

摘要

The Dissolving loss of Nd in the systems NdCl3-MCln（M=Li,Na,K,Ca,Sr,Ba;n=1 or 2）and the NdCl3-rich NdCl3-LiF motlen salts,and in the system of NdCl3-（90 wt% KCl,10 wt%MCln） wasdetermined.It was found that the dissolving loss of Nd (BNd) in the NdCl3-KCl,NdCl3-CaCl2 andNdCl3-（90 wt%KCl,10 wt%CaCl2） melts is rather insignificant.The dissolving loss of Nd in theNdCl3-KCl system increases with temperature,yet it is only 1/3 of that in pure NdCl3 when the content ofNdCl3 was less than 50 wt% in the mixture.Addition of LiF to NdCl3 can diminish the dissolving loss ofNd.The nature of interaction between metallic Nd and its salts was also discussed.
