ELECTRO-CHEMICAL PROCEDURE OF PRODUCTION OF METALLIC TUNGSTEN IN HIGH DISPERSED REACTIVE STATE

摘要

FIELD: metallurgy. ^ SUBSTANCE: procedure consists in electro-chemical sedimentation of tungsten in atmosphere of air from solutions of tungstates in ion liquid with utilisation of metallic tungsten as material of anode. Electrochemical sedimentation is carried out at temperature 50-60C during 5-8 h and current density 2.5-20 mA cm-2. ^ EFFECT: production of high dispersed and reactive metallic tungsten in form of nano-particles with average dimensions 100-200 nm and high area of surface. ^ 3 dwg, 5 ex
