Abstract
Crystallites can grow in superfine zirconia powder during calcination. It is found that, in addition to calcination temperature and holding time, the crystallite size or crystallite growth rate can apparently also be affected by doping. Undoped powder has the largest crystallite size and the size decreases as the dopant content increases under the same calcination conditions. The effect of crystallite growth suppression is also dependent on dopant types, and it is explained by the dopants surface energy reduction effect, which is related to their ability to stabilize tetragonal and/or cubic phases of zirconia and to their surface-enriching and solute-dragging effects.
