Abstract

The concept of tailored interfaces has been applied to the synthesis of nano-scaled Y2O3/ZrO2 powders. The microemulsion technique as well as the thermodynamically controlled growth reaction have been utilized for this purpose. Both methods yielded agglomerate free amorphous powders with particles sizes of 8 nm and 15 nm, respectively. Cubic zirconia was obtained by calcination between 300 and 400 °C and crystallite coarsening was not observed. The calcined powders could be redispersed by treating them with tertiary amines in aqueous solutions.
