Abstract

Nanodispersed composite materials -Fe2O3/-Fe2O3 were obtained by thermal
decomposition of iron citrate xerogel hydrate synthesized by iron nitrate and citrate acid solutions
with different colloidal solutions of Fe(NO3)39H2O and С6Н8О7 Н2О for different molar ratio
between precursors. The influence of the precursors molar concentration and calcination
temperature on the material phase composition, crystalline and magnetic microstructure, surface
condition was studied. Methods of X-ray diffraction, Mössbauer spectroscopy, electron microscopy
and IR - spectroscopy were used.
