Abstract
We have studied the effect of tungstate and molybdate anions on the formation of zirconia polymorphs from amorphous anion-modified zirconium hydroxide during mechanochemical processing. The results demonstrate that the effect of anion additives on the formation of metastable zirconia from amorphous zirconium hydroxide during mechanochemical processing differs in a number of important points from that in thermochemical processes. In thermal processes, anion additives favor the formation and stabilization of nanocrystalline tetragonal zirconia. By contrast, in mechanochemical synthesis, anion additions inhibit the formation of metastable zirconia.
