摘要：

A study was made into the effect of the conditions (synthesis temperature, water content, iron salt(III) concentration, and nature of precipitant) of the synthesis of magnetite nanoparticles by high-temperature reductive hydrolysis of iron(III) salts in an ethylene glycol medium on their size and morphology. It was shown that is basically possible to carry out the direct synthesis of spherical particles with an average size of 55-170 nm while varying synthesis conditions. The obtained particles were characterized by X-ray powder diffraction analysis, and their magnetic properties were explored. The synthesized particles are ferrimagnets. The magnetic moments, numbers, and sizes of domains in magnetite particles of various sizes were found.
