Phase diagram of system SmCl~3-SrCl~2-MgCl~2

Abstract

The phase diagram of the ternary system SmCl3-SrCl2-MgCl2 was investigated by DTA. There are four surfaces corresponding to the primary crystallization of SmCl3, SrCl2, MgCl2, SmSr3Cl9, resp., and five univariant lines related to the secondary crystallization Ternary eutectic point E (41.8 SmCl3, 30.7 mol.% SrCl2, 500? and ternary peritectic point P (32.0 SmCl3, 39.3 mol.% SrCl2, 520? were observed Two equilibrium reactions with four phases exist, namely, LE J SmCl3 + SmSr3Cl9 + MgCl2 LP + SrCl2 J SmSr3Cl9 + MgCl2.

Key words: TERNARY SYSTEM, MAGNESIUM CHLORIDE, RARE EARTH COMPOUNDS, FUSED SALTS, PHASE DIAGRAM, STRONTRIUM CHLORIDE, SAMARIC CHLORIDE
