The Study of Zirconium and Niobium Joint Electrodeposition in KCI-KF-K_2ZrF_6-K_2NbF_7 Melts

摘要

One of the most widely used methods of producing binary Zr-Nb alloys forming solid solutions is alloying of both of the metals by arc melting [1]. However, this method requires several sequential meltings to achieve the ingot's homogeneous. The possibility of a direct production of Zr-Nb alloys codeposition of the components by molten salt electrolysis was pointed out in work [2]. The aim of this work has been studying the joint zirconium and niobium electrodeposition in KC1-KF-K_2ZrF_6-K_2NbF_7 melt and evaluation of the possible changes in the alloy composition during the electrolysis. Prior to studying the joint electrochemical behaviour of Zr and Nb in chloride-fluoride melts it is necessary to establish the mechanism of the cathodic process for individual components.
