摘要
采用循环伏安法,研究了700℃无水和含微量水的等摩尔KCl-NaCl熔体中,Mo,W,Pt及不锈钢电极上镁(Ⅱ)还原过程。由测定的结果推测了其还原机理,探明了水和所用电极材料对镁(Ⅱ)还原的影响,并对各种电极材料在含水体系中的钝化情况进行了比较。
The reduction process of magnesium (Ⅱ) on molybdenum, tungsten, platinumand stainless steel electrodes in NaCl-KCl (equimolar) melt in the presence oftrace water has been investigated. The determination was carried out by cyclicvoltammetry at 700℃. The results revealed the influence of water and electrodematerials on the reduction process of magnesium (Ⅱ). A comparison of the passivation of various electrode material in molten saltsystem containing water has been made. The reduction mechanism has also beendiscussed.
