Summary, etc. α-Fe<sub>2</sub>O<sub>3</sub> nanoparticles have been successfully produced by the wet high-energy ball-milling method.<strong> </strong>Phase and nanostructure characterizations of as-crushed powders have been done by X-ray diffraction and field emission scanning electron microscopy techniques.<strong> </strong>Average particle sizes of 56 and 51 nm are obtained after 20 and 40 hours of wet ball milling process, respectively.<strong> </strong>The catalytic property of the synthesised α-Fe<sub>2</sub>O<sub>3</sub> nanoparticles in the thermal decomposition reaction of ammonium perchlorate has been evaluated by thermogravimetry and differential scanning calorimetry. Thermal analysis confirms that<strong> </strong>adding 5 wt.% α-Fe<sub>2</sub>O<sub>3</sub> nanoparticles (51 nm) decreases the decomposition temperature of ammonium perchlorate from 422.0 °C to 360.0 °C and increases the Δ<em>H</em> of the decomposition reaction from 880 J g<sup>-1</sup> to 1408.1 J g<sup>-1</sup>.<strong> </strong>Finally, the catalytic effects of α-Fe<sub>2</sub>O<sub>3</sub> NPs on kinetic and thermodynamic parameters of thermal decomposition reaction of treated AP particles have been studied by Kissinger, Boswell, Ozawa and Starink methods.
