Electrochemical formation of Mg-La-Mn alloys by coreduction of Mg(Ⅱ),La(Ⅲ) and Mn(Ⅱ) in LiCl+KCl molten salts
文献摘要：
In the present work,cyclic voltammetry (CV),square wave voltammetry (SWV) and chro-nopotentiometry (CP) were used to investigate the electrochemical coreduction behaviors of La(Ⅲ) and Mg(Ⅱ) as well as La(Ⅲ),Mg(Ⅱ) and Mn(Ⅱ) on Mo electrode in LiCl + KCl molten salts.CV and SWV results exhibit that the coreduction mechanism of La (Ⅲ) and Mg(Ⅱ) on Mo electrode is that La(Ⅲ) is reduced and Mg-La intermetallic compound is formed,leading to the deposition potential of La(Ⅲ) shifting to more positive one.The electrochemical signals pertaining to the formation of metallic La,Mg and Mn as well as Mg-La intermetallic compound are also observed by coreduction of La(Ⅲ),Mg(Ⅱ),and Mn(Ⅱ) in LiCl + KCl molten salt on the inert Mo electrode.However,the electrochemical signals associated with the formation of La-Mn and Mg-Mn alloys are not observed,which means that the depolarization effect of La(Ⅲ) and Mg(Ⅱ) does not occur on pre-deposited Mn electrode.The Mg-La-Mn alloys were formed by co-deposition of La(Ⅲ),Mg(Ⅱ),and Mn(Ⅱ) on Mo electrode at various concentration ratios of La(Ⅲ)and Mg(Ⅱ).The results of scanning electron microscopy equipped with energy dispersive spectroscopy and X-ray diffraction displays that the Mg-La-Mn alloys are comprised of La-Mg compound Mg17La2,Mg and Mn phases.The concentration ratio of La(Ⅲ) and Mn(Ⅱ) has few effects on the alloy composition.
