Oxidation of metallic iron with oxygen via mechanochemical activation

The X-ray phase analysis and X-ray diffraction, as well as IR and Mossbauer spectroscopic techniques were employed to study mechanochemical oxidation of iron metal powder with oxygen. The phase composition of the products of mechanochemical activation of iron in a vibrating mill was determined. The extent of oxidation of iron was examined in relation to the particle-size distribution of the starting iron powder.
