METHOD FOR OBTAINING METALLIC RHENIUM BY REDUCTION OF AMMONIUM PERRHENATE Russian patent published in 2014 - IPC C22B61/00

Abstract RU 2511549 C1

FIELD: metallurgy.

SUBSTANCE: method for obtaining metallic rhenium by reduction of ammonium perrhenate involves arrangement of ammonium perrhenate powder in a boat and its reduction by counter current of dry hydrogen with continuous movement of the boat in a tube furnace at the temperature of 300-330°C. Prior to reduction, ammonium perrhenate powder is purged with argon and heated in the tube furnace up to the temperature of 200°C.

EFFECT: method ensures production of rhenium powder that requires no cleaning from impurities, as well as reduction of rhenium powder losses.
