Nanosize alumina, ceria, yttria, zirconia CeO2-ZrO2 (OSC),
(ZTA) and Y2O3-ZrO2 (YSZ) have been prepared by the combustion of aqueous
solutions containing corresponding metal nitrate,
ammonium nitrate and glycine
redox mixtures. The combustion is non-flaming (smoldering)
and yields voluminous
oxides with large surface area (10-30 m2g-1) and nanosize (10-50nm).
Powder XRD and
TEM have been used to characterize the products of combustion.
