摘要： A method for removing oxygen from metal or metalloid oxides, by electrolysis in a fused salt, to produce elements or alloys, improved so as to prevent problems of cell contamination and poor power efficiency, particularly in scaled up electro-deoxidation processes. The cell current, (I), is controlled so that it does not exceed a selected threshold for substantially all of the electrolysis process. The process may comprise a first constant current phase and a second constant voltage phase.

摘要： A method for purifying metal M l particles manufactured by an electrochemical reduction process, the method comprising the steps of introducing the metal M 1 particles into a heat source (13) at a temperature substantially equal to or higher than the melting point of M 1 so as to cause vaporisation of some or substantially all of the contaminating impurities present, removing the vaporised Impurities from the vicinity of the particles, and cooling the purified metal M 1 particles. The purified particles can be used directly in lower temperature powder metallurgy processes and have fully dense spherical particle morphology, imparting good flowability. The purification process can also be incorporated as an integral stage of sheet or stock production processes based on particle feedstock’s that have been produced by electrochemical reduction.
