Abstract
Nanosized particles of gamma -Fe2O3 were prepared by heat treatment of the precipitates, obtained from a homogeneous solution of stearic acid and hydr ated iron(III) nitrate. The compositional and thermal characteristics of th e precipitates were studied with the aid of infrared spectroscopy and diffe rential scanning calorimetry. The x-ray diffraction and small-angle x-ray s cattering investigation shows that theta -Fe2O3 nanoparticles with narrow s ize distribution can be prepared successfully by this route.
