| Abstract: | Zirconium metal was prepared by direct electro-deoxidization of solid ZrO2 cathode plate doped with different amount of graphite powder.Composition and morphology of the cathode were studied after sintering and direct electro-deoxidization.Effects of graphite powder doping on electrode-oxidization reaction were investigated.The results show that graphite powder doping can increase the oxygen vacancy in the sintered samples,improve the reactivity and zirconium metal recovery,and reduce energy consumption. |
