Abstract
The paper describes creation of magnetite nanoparticles under ultrasound treatment and investigation
of their phase composition and magnetic properties. Magnetite nanoparticles were synthesized via coprecipitation
of Fe+2 and Fe+3 with KOH in aqueous solution at 80°C. It was shown, that ultrasound treatment
of solution during the synthesis of magnetite nanoparticles leads to the increasing of size and saturation
magnetization obtained nanoparticles. The results of X-ray diffraction measurements show that the
synthesized particles consist of magnetite. The size of synthesized magnetite nanoparticles according to Xray
diffraction measurements was approximately 10 nm. Saturation magnetization of synthesized magnetite
nanoparticles is rather high (37 A*m2/kg). Synthesized magnetite nanoparticles are promising for different
medical-biological applications.
