摘要

Particles with core-in-shell structure Fe@ZrO_2 were synthesized by step-bystep technology including formation of mechanically pre-activated (MA) precursors with Fe/Zr and Fe_2O_3/[Fe/Zr] composite structures formation following by Self-Propagated High temperature synthesis (SHS). Mossbauer spectroscopy, Transmission and Scanning electron Microscopy have been performed to study the peculiarities of local structure and its evolution through the sequential synthesis steps via various milling periods and reagent compositions. The exact conditions for iron core in oxide shell Fe@ZrO_2 structure formation with promising functionality has been established.
