本文用差热分析法重新测定了组成PrCl_3-NaCl-LiCl三元系的三个侧边二元系相图,测定了该三元系中6个不同组成的变温截面,从而构筑了PrCl_3-NaCl-LiCl三元相图。该三元系由分别对应于PrCl_3,NaCl,2NaCl·LiCl,NaCl·LiCl和LiCl的5个液相面,7条二次结晶线,两个转熔点和一个共晶点构成。转熔点和共晶点的温度和组成分别为:P_1(416℃,30.3mol％NaCl,44.2mol％LiCl,25.5mol％PrCl_3);P_2(409℃,25.0mol％NaCl,50.0mol％LiCl,25.0mol％PrCl_3);E(404℃,20.0mol％NaCl,55.4mol％LiCl,24.6mol％PrCl_3)。二元和三元相图液相限的测量误差约为±5℃和±7℃。     

Determination of Oxide in FLINAK Melt by Electrochemical Titration Technique

The use of K_2NbF_7 as a probe solute for the cyclic voltammetric determination of oxide in FLINAKmelts was studied and demonstrated.This method is based on a complex reaction and the peak current densityof NbF_7~(2-)reduction.The reaction constant was determined to be very large at 973 K.A cyclic voltammetricstandard addition experiment is also employed to determine the amount of oxide in FLINAK melt.The oxidecontent of FLINAK melts is equal to the amount of Nb(V)added minus the amount of NbF_7~(2-)which is ob-tained from the voltammogram.     

Identification of Complex Ions of Nb(V)in FLINAK-O~(2-)System by Infrared Spectra

The FT-IR spectra for K_2NbF_7-FLINAK-O~(2-) solution were measured and compared with the spectraof crystalline K_2NbF_7 and K_2NbOF_6.The results show that the niobium fluoro-complex and/oroxyfluoro-complex ions are presented in these solutions.NbF_7~(2-) complex ion is the predominant species inNb(V)-FLINAK solution(not considering oxide impurity).The influence of O~(2-) on the oxyfluoro-complexions shows that NbOF_6~(3-) as a stable monooxyfluoro-complex anion presented in FLINAK-O~(2-) systemsand the number of NbOF_6~(3-) species are increased with increasing of O~(2-) when molar ratio of O~(2-)/Nb(V)is less than 1.
