Thermally Driven and Ball-Milled Hematite to Magnetite ...
In this work, a study on the dynamics of transformation from hematite (α-Fe 2 O 3 ) to magnetite (Fe 3 O 4 ) by following two solid-state reaction methods is carried out. One of the procedures consists of a thermal treatment under a 20% H 2 and 80% N 2 atmosphere at 375°C, whereas the second method involves a planetary ball mill to induce the transformation.
