Study on the Electrochemical Deoxidation Process of Tantalum in LiCl-NaCl Molten Salt AITranslate
Abstract AITranslate
The electrochemical deoxidation process of tantalum in molten LiCl-NaCl was studied by cyclic voltammetry and constant cell voltage electrolysis,along with SEM,XRD and oxygen-nitrogen analysis techniques.The effect of graphite anode gas on the deoxidation process was investigated.The research results show that in LiCl-NaCl molten salt system,the oxygen content in tantalum can be effectively reduced by electrolysis,and the deoxidation reactions include Ta2O5→Ta(O)+LiTaO3 and Ta(O)+LiTaO3→Ta.The molten salt electrochemical deoxidation process employs electrons as the reducing agent,and 10%oxygen is removed by electrolyzing tantalum powder at-2.8 V for 10 h.Besides,electrochemical deoxidation promotes the sintering of tantalum particles.
