Synthesis and thermal behaviour of nanostructured ZrO2 powders obtained under hydrothermal conditions.
Nanocrystalline zircone (ZrO2) powders were synthesized from zirconium oxyacetate aqueous solution treated up to 240 degrees C under autogeneous pressure. Depending on experimental conditions, colloidal particles of 26-150 nm are formed by aggregation of zirconia crystallites. The effect of some experimental conditions over the colloidal particle size or zirconia phase composition was studied. The powder sintering behaviour is also presented.
