Y(Ⅲ)在镍电极上电沉积及表面合金化

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

摘要: 本文使用循环伏安法,X射线衍射及扫描电镜研究了Y(Ⅲ)在NaCl-KCl-YCl₃熔盐体系,在镍电极上的还原过程。研究结果表明:Y(Ⅲ)在镍电极上还原时,首先形成金属间化合物Ni₅Y及NiY,然后才析出纯金属钇.

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.
