FIELD: chemistry.
SUBSTANCE: invention relates to production of nanosized copper (II) ferrite powder. Method involves preparing a reaction solution, obtaining a precipitate in powder form, separating, drying and calcining it. Reaction solution is prepared by dissolving a mixture of salts of copper (II) nitrate and iron (III) nitrates taken in stoichiometric molar ratio (1:2) in 10 % dextran 40 solution or 6 % dextran 70 solution. Powder is obtained by mixing the obtained reaction solution with the strongly basic gel anionite AV-17-8 or A-400 in a hydroxyl form at temperature of 60 °C for 1 hour. Roasting is carried out at temperature 800 °C for 2 hours.
EFFECT: obtaining single-phase nanosized copper (II) ferrite powder.
