An investigation on phase diagram of systems NdCl3-LiCl and NdCl3-LiCl-NaCl

Abstract

DTA and x-ray anal. methods were used to study the title systems. Phase diagrams are constructed. The NaCl3-LiCl system is eutectic, with eutectic point at 28.5 wt.% LiCl and 452? A metastable compound, LiNd2Cl4, is formed on the solid state and decomps. >443? In the ternary system NdCl3-LiCl-NaCl, the eutectic composition is 69.0 (wt.%) NdCl3, 13.5 NaCl, at 374? Two ternary peritectics are observed, at 380 and 385? resp., containing (wt.%) 69.5 and 70.0 NdCl3 and 14.5 and 15.5 NaCl, resp.

Key words: BINARY SYSTEM, CHLORIDE, X-RAY DIFFRACTION ANALYSIS, TERNARY SYSTEM, LITHIUM COMPOUNDS, SODIUM CHLORIDE, DIFFERENTIAL THERMAL ANALYSIS, FUSED SALTS, NEODYMIUM CHLORINE, PHASE DIAGRAM
