FIELD: chemistry.
SUBSTANCE: method for obtaining magnetite involves precipitation of iron (II) hydroxide from FeSO4 sulfate and its oxidation by nitrate ions to magnetite Fe3O4 while thermostating. Thermostating is carried out for 0.083-24 hours. Precipitation is carried out at a temperature of 10-22°C, and oxidation at 37-40°C.
EFFECT: invention makes it possible to obtain magnetite nanoparticles with an average size of 42 to 81 nm and a narrow size distribution.
