Surface| Zusammenfassung: | Methods of synthesis of hollow spherical nanosized particles of magnetite have been developed and tested.  The general approaches to the formation of such particles with the specified structure and morphology have been determined. The structure, phase and elemental composition, and morphology of the fabricated particles have been studied by X-ray phase structure analysis, Auger-electron spectroscopy, scanning electron microscopy and atomic force microscopy. The magnetic characteristics have been studied by the induction method with a vibration magnetometer. We have found that the methods developed allow us to fabricate the hollow and porous spherical particles of magnetite of 40 nm to 200 nm in diameter with wall thickness of about 1/10 d and narrow diameter distribution. |
