INSTRUMENT FOR IODIDE REFINED HAFNIUM Russian patent published in 2009 - IPC C22B34/14 C22B9/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to receiving of exceptionally pure hafnium, particularly it relates to devices for hafnium receiving by method of iodide refining and can be also used for receiving of other iodide metals. Instrument for hafnium iodide refining contains closed by pressurising cover thermostatically controlled retort with peripheral area for filling up of initial raw materials, wire from refractory metal of curly form, degassing system, facility for iodine feeding into retort. Peripheral area for filling up of initial raw materials is implemented in the form of installed by the perimeter retorts stacked metal shelves. Wire made of refractory metal is implemented in the form of four loops, each of which is suspended through the adapter to two current contact jaw. Current contact jaws are paired.

EFFECT: increasing of yield metal during the process of hafnium iodide refining, reduction of cost price of the received metal.
