Nanopartide zirconia

In addition to purely mechanical comminution, mechanochemical processing has been employed for the preparation of nanoscale zirconia. Here, McCormick and coworkers obtained nanopartides of 4—6 nm by the reaction of ZrCh with II2O or MgO in a vibratory mill under an argon atmosphere to afford Zr02 and liCl/ MgCh, which could be crystalhzed at moderate temperatures [110, 111].

Of course, clay particles are not the only nanofiDers used today. Other nanofillers include carbon particles (carbon black and carbon nanotubes), various inorganic oxides (zirconia, titania, silica, etc.), metal nanopartides (gold, silver), and some other, more exotic ones (e.g., polymeric nanopartides such as dendrimers). In general, we can distinguish nanopartides by...
