(东北大学材料与冶金学院， 沈阳 110006)
摘 要: 采用循环伏安法和计时电位法研究了钪离子在1043K下、LiF-NaF体系中银电极上的阴极还原过程。结果表明，Sc3+在Ag电极上的还原过程是可逆的简单电荷传递的三电子反应，阴极过程受扩散控制。

REDUCTION MECHANISM OF Sc3+ ION ON Ag ELECTRODE IN FLUORIDE SALT MELT
（School of Materials & Metallurgy, Northeastern University, Shenyang110006）
Abstract:The reduction mechanism of Sc3+ ion on Ag electrode in LiF-NaF system at 1043 K was investigated with the cyclic voltammetry and chronopotentiometry. The results showed that the cathode reduction reaction is the reversible process with a simple 3-electron transfer, and is controlled by diffusion.
