<jats:title>Abstract</jats:title><jats:p>Mechanical activation of MgO in a planetary mill results in structural changes comparable to those observed in a vibration mill. Under the given conditions they are, however, achieved in considerable less time. Furthermore, a so far unreported lattice dilatation could be observed. The activated MgO showed an increased reactivity with respect to the ambient atmosphere. As a result magnesium hydroxide and a basic magnesium carbonate are formed.</jats:p>
