Abstract the path of the reaction between fe2o3 and si activated by high energy ball milling has been investigated by xray diffraction and m ssbauer spectroscopy hematite reduction involves oxygen transfer from fe to si with the formation of intermediate phases containing feii which are then reduced to fe0 a steady state is reached in the milling process where the reduction of
The patterns of the starting and ballmilled powder after 10 h showed only the presence of fe 2 o 3 phase however new diffraction peaks for the phase fe 2 o 3 or fe 3 o 4 were observed at the milling time of 20 h and the phase coexisted with fe 2 o 3 for prolonged ballmilling time
The transformation of hematite to magnetite by highenergy ball milling in a sealed container has been studied by mossbauer spectroscopy and xray diffraction mechanisms for this transformation are critically discussed the dominant mechanism is concluded to be due to bond breaking during the high energy ball milling followed by release of the
