Title: Oxide solubilities and phase relations in the system Mg-Nd-O-Cl

Abstract

Freezing point depression measurements have been performed for the CaCl{sub 2}-NdOCl, Cs{sub 2}MgCl{sub 4}-NdOCl and MgCl{sub 2}-NdOCl liquid binaries with small additions of NdOCl. Very low NdOCl solubilities are observed in all the three binaries. Calculated solubility products of NdOCl at 1,073 K in CaCl{sub 2} and Cs{sub 2}MgCl{sub 4} are in the range 10{sup {minus}6}--10{sup {minus}8} confirming the experimental data.The MgCl{sub 2}-NdOCl system is more complicated. In the very dilute region NdOCl dissolves by forming two foreign ions probably Mg{sub 2}OCl{sub 5}{sup 3{minus}} and Nd{sup 3+} or NdO{sup +} and Mg{sub n}Cl{sub m}{sup (2n-m)-} depending on which cation Mg{sup 2+} or Nd{sup 3+} will bond the O{sup 2{minus}} ion most strongly.
