Reaction of lithium oxide with neodymium chloride was studied in LiCl, LiCl–KCl and NaCl–KCl based melts at various O2– : Nd3+ mole ratios. The effect of the experimental conditions on the degree and rate of neodymium precipitation, phase composition of the solid reaction products was investigated. Size of the particles in the precipitates formed at various conditions was determined to assess the feasibility of subsequent separation of the solids from the technological melts.

Activity, activity coefficients, and solubility of lanthanum and praseodymium in Ga-In eutectic alloy (21.8 wt.% In) were determined between 573 and 1073 K employing the e.m.f. method. In addition activity of these metals was also determined in alloys with indium in the same temperature range.
