Extraction of Rare Earth from La–Ni Alloys by the Glass ...

 · The use of the glass slag method in the extraction of rare earth from La–Ni alloys was studied. X-ray diffraction and electron probe microanalysis studies revealed that the La–Ni alloys produced by the glass slag method using boron trioxide consisted of Ni and Ni 3 B phases. No La-containing phase such as the LaNi 5 phase and the La oxide phase was found in the resultant alloys.
