摘要:The Fe(OH)3 precursor was prepared by solid -state reaction with Fe(NO3)3·9H2O, NaOH and disethylene 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 diffraction, 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.
