摘要
Metal zirconium was prepared by electro-deoxidization method. Using CaCl2 molten salt as electrolyte,sintered ZrO2 pallets as cathode,graphite rod as anode,the pallets were electrolyzed at 900 ℃ and 3.1 V for 8,10 and 12 h,respectively. The mechanism of electro-deoxidization of ZrO2 was studied preliminarily. The results show that the morphologies of cathode pallets affect the forming process of products. The process of electro-deoxidization of ZrO2 in the molten salt is conducted step by step,from exterior of cathode to its interior and from high valence oxide to low valence oxide until to metal.
