Preparation of Zirconium by Electro-Deoxidization in Molten Salt

Li Qingyu Du Jihong Xi Zhengping (Northwest Institute for Nonferrous Metal Research,Xi'an 710016,China)  
Metal zirconium was prepared by electro-deoxidization method.Using CaCl_2 molten as electrolyte,sintered ZrO_2 pallets as cathode and graphite rod as anode,the pallets were electrolyzed at 900℃at 3.1 V for 8,10 and 12 h.The mechanism of electro-deoxidization of ZrO_2 was studied preliminarily.It was found that the morphology of cathode pallets effect the forming process of products.The process of electro-deoxidization of ZrO_2 in the molten salt was conducted step by step,from exterior of cathode to its interior and from high valence oxide to low valence oxide until to obtain metal.The metal zirconium content of the product was up 93wt% on electrolyted for 10 h,mainly because was the existence of Zr-O solid solution in the pallet,but even if the electrolyze time was longer, the solid solution of O in Zrconium counnot be deoxidized completely.
