摘　　要：The reduction of Tm(Ⅲ) on a liquid Zn electrode was investigated in a Li Cl-KCl melt via cyclic voltammetry,square wave voltammetry, and open circuit chronopotentiometry. On a liquid Zn electrode, the reduction mechanism of Tm(Ⅲ) ions is through one step with the exchange of three electrons via the formation of a Zn-Tm alloy. This differs from that on an inert electrode, as the reduction is Tm(Ⅲ) ions were though two consecutive steps. Galvanostatic electrolysis was carried out at a liquid Zn electrode at different current densities in a LiClKCl-TmCl3 melt. The Tm2Zn17 intermetallic compound was identified in the deposit, except in the Zn phase,by X-ray Diffraction(XRD).The reduction of Tm（III） on a liquid Zn electrode was investigated in a LiCl-KCl melt via cyclic voltammetry, square wave voltammetry, and open circuit chronopotentiometry.
