FIELD: metallurgy.
SUBSTANCE: invention relates to hydrometallurgy of lanthanides, particularly, to crystalline nanopowders of lanthanide oxides. Proposed method comprises deposition of lanthanide salts from nitric solutions of solid oxalic acid at continuous introduction of polyacrylamide, its separation, flushing, drying, heat treatment of produced sediment and subsequent treatment in weak alternating magnetic field at 20-50 Hz and with amplitude of 0.05-0.1 tesla.
EFFECT: nanosized particles with uniform grain sizes, higher water resistance.
