Iron-Based Amorphous Magnetic Phase Formation In The Course Of Fe And Fe_2O_3 Mechanical Activation

摘要

Solid phase high energy mechanochemical interaction of α-Fe_2O_3(hematite) and Fe in powder mixture have been studied. The formation of amorphous iron-based magnetic phase in this process was detected by means of Mossbauer spectroscopy and magnetic measurements. The amount of this phase increases with Fe addition in reduced mixture. Its thermal stability have been studied by magnetic and DCS measurements at constant α-Fe_2O_3 and gradually increased Fe concentrations.
