Mechanochemical reactions of ilmenite with different additives

Different mechanochemical reactions between ilmenite (FeTiO 3 ) and elemental powders have been observed during high-energy ball milling, where the ilmenite has been reduced to crystalline iron, nanocrystalline oxides and amorphous phases at room temperature. The processes of the mechanochemical reactions were investigated by X-ray diffraction analysis and differential thermal analysis. The observed mechanochemical reactions seem to occur under high-energy ball impacts and are different from the corresponding thermally activated reactions.
