PROCEDURE FOR PRODUCTION OF POWDER OF HIGH-MELTING METAL Russian patent published in 2010 - IPC C25C5/04 B22F9/18 

Abstract RU 2401888 C1

FIELD: metallurgy.

SUBSTANCE: procedure consists in electro-chemical reduction of salt of high melting metal in melt of electrolyte in electrolyser by mixing it in pressure tight inert atmosphere. Also, there is used electrolyser with an anode and cathode made of metal of produced powder. As electrolyte there is used an equimolar homogenous mixture of chlorides of alkali metals. Notably, reduction is performed under isothermal conditions at direct current with cathode density from 0.01 to 1.0 A/cm2; alkali metal soluble in electrolyte is extracted on the cathode, while salt of settled high melting metal is extracted on the anode; salt is reduced to metal powder of high melting metal by interaction with at least one of sub-ions of alkali metal. Metal produced in electrolyte is extracted, crushed and washed.

EFFECT: production of powders with specified fractions and types of structure.
