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.
