| Abstract: The Fe(OH)3 precursor was prepared by solid -state reaction with Fe(NO3)3·9H2O, NaOH and dispersed poly-ethylene glycol at low heating temperature(25 ℃). Synthesis of iron oxide (γ-Fe2O3) nanoparticle was achieved by thermal decomposition of Fe(OH)3·xH2O precursor. The nanoparticle was characterized by TG-DTA, X-ray diffra-ction, TEM etc. The results showed that the nanoparticle was composed of γ-Fe2O3 and was a better absorber for electromagnetic wave within the low frequency band. |
