METHOD OF PURIFYING ZIRCONIUM TETRAFLUORIDE FROM ADMIXTURES Russian patent published in 2014 - IPC C22B34/14 C22B9/00

Abstract RU 2512726 C2

FIELD: chemistry.

SUBSTANCE: invention relates to metallurgy. Method of purification of zirconium tetrafluoride from admixtures includes sublimation of zirconium tetrafluoride in mixture with 8-30 wt % of metal zirconium and desublimation of formed vapour. Crushed waste products in form of shavings, chips, filings and skull can be used as metal zirconium.

EFFECT: efficient purification of zirconium tetrafluoride from admixtures is ensured.
