Spectrophotometric study of Nd$$^{2+}$$ ions in LiCl-KCl eutectic melt

Hayashi, Hirokazu ; Akabori, Mitsuo; Ogawa, Toru; Minato, Kazuo 

UV and visible spectrophotometric study was made in order to prove the existence of Nd$$^{2+}$$ ion and clarify the equilibrium among Nd metal, Nd$$^{2+}$$, and Nd$$^{3+}$$ ions in LiCl-KCl eutectic melt. Spectra assigned to Nd$$^{2+}$$ ion were observed for NdCl$$^{2+}$$ in (LiCl-KCl)$$_{eut.}$$ and Nd- NdCl$$_3$$ 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 Nd$$^{2+}$$ ion were observed. X-ray diffraction measurements and electron-probe micro-analyses of the corroded glass cells revealed that the corrosion products contained NdOCl.
