摘要
采用循环伏安法和记时电流法研究800-860℃下ZrO2电极在CaCl2-NaCl熔盐中还原过程的反应机理.ZrO2电极在CaCl2-NaCl熔盐中的循环伏安曲线和XRD物相分析结果表明,可以通过直接电脱氧法由ZrO2制备金属Zr,并且ZrO2的还原分步进行,ZrO2先还原为ZrO,ZrO再还原为Zr.
The mechanism of ZrOz direct electrodeoxidation into Zr in CaCl2-NaCl molten salt was studied by Cyclic Voltammetry and Chronoamperometry in the temperature range of 800 -860℃. The results of V-A curves, SEM and XRD analysis showed that ZrOz could be reduced to Zr by direct electrodeoxidation and the reduction proceeds in two steps： ZrO2 was firstly reduced to ZrO, and then, ZrO was further reduced to Zr.
