Method embodiments for making lanthanide metal complexes from lanthanide metal oxides and separating the same from heavy lanthanide metal oxides, actinide oxides, and non-lanthanide rare earth element oxides
Patent
·
OSTI ID:1998396
The present disclosure is directed to method embodiments for making anhydrous lanthanide halide complexes. At least some embodiments comprise making a lanthanide halide complex by reacting a lanthanide metal oxide with an oxygen scavenger and catalyst in the presence of a donor solvent. The method is selective toward light lanthanide metal oxides and thus further provides a method for separating light lanthanide metal oxides from heavy lanthanide metal oxides, actinide oxides, and non-lanthanide rare earth element oxides.
