Phase diagram of system NdCl3-LiCl-KCl. Technical report

It is obvious that investigations on phase diagrams of molten salts of rare earth chlorides systems are very important for electrolytic production of rare earth metals. But only a few references are related on these subjects and no phase diagram on NdCl3-LiCl-KCl system has been reported in literature. Related phase diagrams on binary systems of NdCl3-KCl(1) and KCl-LiCl(2) was reported decades ago. Before determining the ternary phase diagram, the authors studied the literatures on phase diagrams of two binary systems, and determined the phase diagram of NdCl3-LiCl(3). On these bases the authors investigate the ternary phase diagram of NdCl3-LiCl-KCl system.
