摘要：

A UV and visible spectrophotometric study was made in order to prove the existence of Nd2+ and clarify the equilibrium among Nd metal, Nd2+, and Nd3+ in LiCl-KCl eutectic melt. Spectra assigned to Nd2+ were observed for NdCl2 in (LiCl-KCl)(eut.) and Nd- NdCl3 in (LiCl-KCl)(eut.) melts. Black corrosion products were observed on the surface of the glass cells used for the measurements, where the spectra assigned to Nd2+ were observed. X-ray diffraction measurements and electron-probe micro-analyses of the corroded glass cells revealed that the corrosion products contained NdOCl.
