Template synthesis of e-Fe2O3 nanoparticles in opal-like matrices

摘要

Nanoparticles of epsilon-Fe2O3 were obtained by template synthesis in the pores of opal-like matrices. The maximum content of epsilon-Fe(2)O(3 )is achieved upon calcination at 1000 degrees C for 2-4 h. The content of epsilon-Fe2O3 in a mixture of modifications of iron oxides reaches 80-90, which is confirmed by the data of X-ray diffraction analysis, Mossbauer spectroscopy and magnetometry experiments.
