Correlation between coprecipitation reaction course and magneto-structural properties of iron oxide nanoparticles

Popis výsledku v původním jazyce

The effect of coprecipitation reaction course on the magneto-structural properties of iron oxide nanoparticles and, as a consequence, on their heating ability in alternating magnetic fields allowed in magnetic hyperthermia was studied. The parameters ofcoprecipitation reaction are chosen to ensure the repeatability of nanoparticles features: narrow size distribution, high crystallinity, and magnetic properties. It is established that the reaction should be carried out in an alkaline medium with slow addition of a solution of iron (II) and iron (III) salts to excess alkali. This provides a simultaneous homogeneous nucleation and a rapid growth of nanocrystals during the first minutes of the reaction. After that the reaction proceeds to the stage of slow growth of nanoparticles, which continues up to the complete exhaustion of the solution of salts. Nanoparticles unite in aggregates during the synthesis. The particles in aggregates are characterized by average size of 13 nm and polydisp
