UV and visible spectrophotometric study was made in order to prove the existence of Nd ion and clarify the equilibrium among Nd metal, Nd, and Nd ions in LiCl-KCl eutectic melt. Spectra assigned to Nd ion were observed for NdCl in (LiCl-KCl) and Nd- NdCl in (LiCl-KCl) melts. Black corrosion products were observed on the surface of the glass cells used for the measurements, where the spectra assigned to Nd ion were observed. X-ray diffraction measurements and electron-probe micro-analyses of the corroded glass cells revealed that the corrosion products contained NdOCl.
