FIELD: chemistry.
SUBSTANCE: method involves anodic dissolving the metallic aluminium in the sodium chloride solution with the concentrationof 29±0.5 g/l in a coaxial electrolytic cell with electrode areas differing on two or more orders with the anodic current density of 20-160 A/m2 in the presence of zirconium ions in an amount providing the zirconium oxide content in the formed precipitate from 5 to 20 wt %, maintaining the resulting precipitate in the mother liquor for at least 48 hours, filtering and drying the sediment.
EFFECT: method allows to obtain highly dispersed aluminium-zirconium oxide systems with an average particle size of 20-50 nm, which can be used for producing ceramics of special purpose.
