Abstract

Mechanical activation is an efficient method to synthesize nanostructure materials. This research is focused on the production of nanostructure spinel (MgAl2O4) powder using the ball milling process. For this purpose, a mixture of gibbsite and lansfordite powders was subjected to planetary ball milling. The obtained powder particles after different milling times and various heat treatment histories were evaluated by X-ray diffractometry (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The results showed that single-phase nanostructure spinel powder can be obtained after 6 and 10h ball milling with respective annealing at 1000 and 1200°C for 1h.
