Electrolysis can only be prepared in general industrial grade rare earth metals, such as the preparation of low impurities, high purity metal, generally by vacuum heat reduction method to prepare. Rare earth oxide is usually made of rare earth fluoride, in the vacuum induction furnace with metal calcium reduction, made of crude metal, and then after remelting and distillation to obtain more pure metal, this method can produce all the single Rare earth metals, but samarium, europium, ytterbium, thulium can not use this method.vacuum nitrogen furnace vacuum argon furnace
The oxidation-reduction potential of samarium, europium, ytterbium, thulium and calcium only partially reduced the fluorinated rare earth. The general preparation of these metals is the use of the high vapor pressure of these metals and lanthanum metal low vapor pressure principle, the four kinds of rare earth oxides and lanthanum metal debris mixed briquettes, in a vacuum furnace reduction, lanthanum comparison Lively, samarium, europium, ytterbium, thulium is reduced to lanthanum after the metal collected in the condenser, and slag is easy to separate.Horno de soldadura al vacío de tama?o peque?o hasta 1400c
