摘要
本文用循环伏安法研究了钨酸钠在LiCi-NaF(80—20mol％)熔盐体系中的电化学还原过程,并用X射线衍射法检测了由恒电位电解得到的阴极产物。结果表明,钨酸钠的还原分两步进行,W(Ⅵ)首先经二电子还原成W(Ⅳ),再经四电子还原成W(0)。
The processes of electrochemical reduetion of tungstate in LiCl-NaF (80—20 mel%) melts at 680℃ by use of cyclic voltametry has been studied. The cathodie products obtained by potentiostatic electrolysis were examined by X-ray diffraction. The results indicate that the tungstate is reduced in twe steps, undergoes a two electron reduction to W(Ⅳ) followed by a four electron reduction to W(0).
