Zirconia nanoceramic via redispersion of highly agglomerated nanopowder and spark plasma sintering.

A 2.7 mol% yttria stabilizing tetragonal zirconia (2.7Y-TZP) nanopowder was synthesized and stored for five years.

Effect of starting powders on the sintering of nanostructured ZrO ceramics by colloidal processing.

The effect of starting powders on the sintering of nanostructured tetragonal zirconia was evaluated. Suspensions were prepared with a concentration of 10 vol.% by mixing a bicomponent mixture of commercial powders (97 mol.
