摘要：

Nanocomposites alpha-Al2O3-Fe containing 75 vol% Al2O3 have been obtained by reaction milling, in a vibratory ball mill, a stoichiometric excess of alumina with aluminum and hematite. The kinetics of synthesis of the nanocomposite has been studied for milling times between 15min and 8h The reduction reaction is completed in about 2h with formation of alpha-Al2O3, iron, hercynite (FeAl2O4) and clusters of Fe in alumina The reaction rate appears moderated by the alumina excess.
