Y(Ⅲ)在鎳電極上電沉積及表面合金化

Electrode Process of Y(Ⅲ) On Nickel Electrode and Surface Metalliding

摘要: 本文使用循環伏安法,X射線衍射及掃描電鏡研究了Y(Ⅲ)在NaCl-KCl-YCl₃熔鹽體系,在鎳電極上的還原過程。研究結果表明:Y(Ⅲ)在鎳電極上還原時,首先形成金屬間化合物Ni₅Y及NiY,然后才析出純金屬釔.

Abstract: the electrode process of Y(Ⅲ) on nickel electrode in NaCl-KCl-YCl₃ molten salts has been investigated by means of cyclic voltammetry, X-ray diffraction and SEM. The results show that intermetallic compound (Ni₅Y and NiY) are formed first, then metallic yttrium is reduced.
