【Abstract】 The basic thermodynamic conditions of the process on producing ytterbium metal from the enriched oxides of Thulium,Ytterbium and Lutecium by La-reduction and Ce reduction have been calculated and reduction experiments were successfully carried out. The experiment results showed that under proper technical conditions, the ytterbium metal of more than 98% purity could be obtained in laboratory with direct recovery of 85%～90%.In this paper, behaviour of main rare earths components and other impurities during the reduc tion and their distribution in products have been investigated. Application comparison between La-reduction and Ce-reduction was breifly made.更多还原
