电解制备镁及镁合金新型电解质物理化学性质的研究

Study on physico chemical properties of new electrolytes in preparation of the electrolytic process of magnesium and its alloys

主要采用MgCl2-NaC1-KCl-CeCl3体系为研究对象,通过改变稀土CeCl3的含量,对熔盐初晶温度、电导率、密度等物理化学性质的影响进行了研究与探讨;并讨论了温度对熔盐密度和电导率的影响;确定了最佳CeCl3含量为5%,得到了电解制备金属镁及镁合金的新型电解质。

Using MgCl2-NaC1-KCl-CeCl3 system for the study in this paper,we have discussed that CeCl3 content impacts on some physical and chemical properties of molten salt such as liquidus temperature,conductivity,density;And effect of temperature on density and electrical conductivity of molten salt was discussed;Finally,we have prepared a new type of electrolyte of electrowinning magnesium metal and magnesium alloys,in which CeCl3 content is 5%.
