PROCEDURE FOR PRODUCTION OF ULTRA-MICRO-DISPERSED POWDER OF NICKEL OXIDE

摘要

FIELD: metallurgy. ^ SUBSTANCE: procedure consists in electrolysis with asymmetrical alternate current of 50 Hz frequency at heating in alkali medium. Electrolysis is carried out at density of current of anode and cathode half-periods 2.5 A/cm2 and 0.5Ç2 A/cm2 correspondingly, while size of parts of produced nickel oxide is 9Ç20 nm. ^ EFFECT: production of ultra-micro-dispersed powder of nickel oxide applicable for usage in catalytic production of nano carbon materials by pyrolysis of hydrocarbon raw stock. ^ 2 cl, 4 ex
