A similar tendency related to structural changes was observed during grinding of talc and pyrophyllite. In these cases, dry grinding in a planetary ball mill deteriorated their structure, which became highly disordered, (Sugiyama et al. 1994). Fine grinding of talc has produced an altered and amorphous structure after less than 30 min.
