The Dissolving loss of Nd in the systems NdCl_3-MCl_n(M=Li,Na,K,Ca,Sr,Ba;n=1 or 2)and the NdCl_3-rich NdCl_3-LiF motlen salts,and in the system of NdCl_3-(90 wt% KCl,10 wt%MCl_n) wasdetermined.It was found that the dissolving loss of Nd (B_(Nd)) in the NdCl_3-KCl,NdCl_3-CaCl_2 andNdCl_3-(90 wt%KCl,10 wt%CaCl_2) melts is rather insignificant.The dissolving loss of Nd in theNdCl_3-KCl system increases with temperature,yet it is only 1/3 of that in pure NdCl_3 when the content ofNdCl_3 was less than 50 wt% in the mixture.Addition of LiF to NdCl_3 can diminish the dissolving loss ofNd.The nature of interaction between metallic Nd and its salts was also discussed.
The Dissolving loss of Nd in the systems NdCl_3-MCl_n (M = Li, Na, K, Ca, Sr, Ba; n = 1 or 2) and the NdCl_3-rich NdCl_3-LiF motlen salts, and in the system of NdCl_3- (90 wt% KCl, 10 wt% MCl_n) wasdetermined. It was found that the dissolving loss of Nd (B_ (Nd)) in the NdCl_3-KCl, NdCl_3-CaCl_2 andNdCl_3- (90 wt% KCl, melts is rather insignificant. The dissolving loss of Nd in the NdCl_3-KCl system increases with temperature, yet it is only 1/3 of that in pure NdCl_3 when the content of NdCl_3 was less than 50 wt% in the mixture. Addition of LiF to NdCl_3 can diminish the dissolving loss ofNd.The nature of interaction between metallic Nd and its salts was also discussed.
