A new simple hydrothermal preparation of nanocrystalline magnetite Fe3O4
Source abstract
Abstract
Nanocrystalline magnetite particles have been prepared by hydrothermal reaction of ferrous sulfate (FeSO4), sodium hydroxide and sodium thiosulfate (Na2S2O3) at 140°C. X-ray powder diffraction pattern indicates that the product is single-phase magnetite in an inverse cubic spinel structure. Its composition is determined by traditional chemical analysis combined with X-ray photoelectron spectroscopy. Transmission electron microscopy images show that the magnetite particles are homogenous in the shape of quasi-sphere polyhedron with average diameter of 50 nm.
