Аннотация:Nanoparticles of e-Fe2O3 were obtained by template synthesis in the pores of opal-like matrices. The maximum content of e-Fe2O3 is achieved upon calcination at 1000°C for 2–4 h.The content of e-Fe2O3 in a mixture of modifications of iron oxides reaches 80–90%, which is confirmed by the data of X-ray diffraction analysis, Mössbauer spectroscopy and magnetometry experiments.
