Nanoparticles of magnetite Fe3O4 were synthesized by thermal reduction of hematite α-Fe2O3 powder in the presence of high boiling point solvent. The structural transformations and magnetic properties of the obtained nanoparticles were investigated by the 57Fe Mössbauer spectroscopy, X-ray diffraction, and magnetic measurements. The content of hematite and magnetite phases was evaluated at each step...
Metastable α-Fe2O3-MO2(M: Sn and Ti) solid solutions can be synthesized by mechanical alloying. The alloy formation, microstructure, and gas sensitive properties of mechanically milled α-Fe2O3-SnO2 materials are discussed. Tin ions in α-Fe2O3 are found to occupy the empty octahedral holes in the α-Fe2O3 lattice. This interstitial model can also describe the structure of α-Fe2O3-TiO2solid solutions...
