ABSTRACT:
A method for preparing ultra-pure metal tetrafluorides in which 3d such as Fe impurities are separated from impure material by a combined vaporization-electrolytic separation procedure. Sublimation and distillation methods are disclosed in combination with electrolytic separation by both emf-series displacement (ESD) and direct melt electrolysis (DME).
