FIELD: metallurgy.
SUBSTANCE: method comprises production of the nickel oxide powder from metal nickel electrodes by electrolysis in basic solution of sodium hydroxide. Process is executed at temperature 20-30°C upon simultaneous action on the electrodes of current with frequency 20 Hz. At that electrolysis is performed at asymmetrical alternating current with current density of anode and cathode half cycle 2.5 A/cm2 and 1 A/cm2, respectively, and at action on the electrodes of the ultrasound radiation with frequency from 150 to 300 kHz.
EFFECT: production of ultra-micro-dispersed powder of nickel oxide suitable for use during catalitic production of nano-carbon materials with maximum production of the target product, decreasing of power consumption.
