An approach is suggested to synthesize the ε-Fe2O3 particles supported on silica with the mean size of few nanometers, narrow size distribution and no admixture of any other iron oxide polymorphs. The facile synthesis is based on the pore filling impregnation method by iron sulfate (II) water solution with the following annealing procedure at ~1173K. It is shown that the ε-Fe2O3 nanoparticles obtained are stable up to ~1173K and possess superparamagnetic behavior up to ~870K.
