METHOD OF REFINING HIGH-MELTING METALS AND ALLOYS Russian patent published in 2001 - IPC

Abstract RU 2168554 C2

FIELD: metallurgy. SUBSTANCE: method comprises melting metals and alloys to be refined in inert atmosphere in the presence of metal which, during melting process, incorporates admixtures to form individual immiscible phase, and removing said phase. In order to reduce content of metal admixtures, metal which incorporates admixtures is metal selected from group consisting of rare-earth metal, yttrium, scandium or mixture thereof in amount sufficient to form individual metal phase which extracts metal admixtures. EFFECT: more efficient refining method. 8 cl, 2 ex
