ABSTRACT:
High purity metal fluorides (ZrF.sub.4, HfF.sub.4, AlF.sub.3) are produced by incomplete reaction of metal or their compounds with elemental fluorine and subsequent elevated temperature sublimation of the metal fluoride from the reaction products wherein unreacted metal or metal compounds act as "getters" to convert volatile impurity metal fluorides to non-volatile metals or metal compounds.
