用循环伏安法和计时电位法研究了YCl_3-KCl·NaCl熔体中Y~(3+)在钼和镍电极上的电极过程。Y~(3+)的还原是分步反应过程:Y~3+c=Y~(2+),Y~(2+)+2c=Y。Y~(3+)在镍电极上还原后能与镍形成合金,对不同条件下形成的合金组成进行了X射线分析。
The cyclic voltammetry and chronopotentiometry were used to study the electrode process of Y ~ (3+) on molybdenum and nickel electrodes in YCl_3-KCl · NaCl melt. The reduction of Y ~ (3 +) is a stepwise reaction process: Y ~ 3 + c = Y ~ (2 +), Y ~ (2 +) + 2c = Y. Y ~ (3+) can be alloyed with nickel after reduction on nickel electrode, and the composition of the alloy formed under different conditions was analyzed by X-ray.
