Study of the Phase Composition of Fe2O3 Nanoparticles

2009 
The changes of the phase composition of iron oxide samples prepared by solgel method using single precursor both for nanoparticles and the matrix were studied by x-ray diffraction. Obtained data were analyzed by an approach using the Debye formula which is suitable for the size of particles up to about 10 nm. The phase composition of the nanoparticles was described by a core-shell model corresponding to the assumed inward movement of the phase interface between two phases. First results of the phase composition of Fe2O3 nanoparticles have already been obtained.
