Resumen:
Physicochemical and structural changes induced by mechanical activation of Al–Fe3O4 mixtures are studied. After 37 min, the system undergoes a self-sustained reaction with formation of a-Fe, FeAl2O4 and a-Al2O3. The evolution of the composition follows a three-step reaction. The solid solution spinel Fe[Al2-xFex]O4, (0:13 < x < 0:29), is obtained through a mechanochemical-thermal route
