Abstract
Neodymium oxide titration was investigated in the LiF-NdF3-Nd2O3 melt on platinum electrode by square wave voltammetry (SWV) in order to develop an in-situ and fast technique for oxide amount monitoring during Nd or Nd-Fe production by electrolysis. The methodology was verified by elemental analyses in the 850–1050 °C temperature range and then applied to Nd2O3 solubility determination in LiF-NdF3.
