Cathodic behavior of scandium(Ⅲ)on reactive copper electrodes in LiF-CaF2 eutectic molten salt
文献摘要：
The electrochemical formation of Sc-Cu alloy was investigated in LiF-CaF2 eutectic molten salt employing various electrochemical methods.Cyclic voltammetry and square wave voltammetry indicate that the reduction of scandium(Ⅲ)on the tungsten electrode is a one-step reduction process with three electrons transfer.And underpotential deposition of scandium on the copper electrode occurs owing to the depolarization effect,i.e.,forming Sc-Cu intermetallic compounds.The thermodynamic properties of the Sc-Cu intermetallic compounds ScCu4,ScCu2,and ScCu in the temperature range of 1153-1223 K were estimated by open-circuit chronopotentiometry.Moreover,the Sc-Cu alloys were prepared by potentiostatic electrolysis and characterized by optical microscope,X-ray diffraction,scanning electron microscopy,and energy dispersive spectroscopy.The results reveal that only Sc-Cu alloy composed of Cu-ScCu4 can be synthesized at low cathodic current density and above eutectic temperature.
