Abstract
HfO2 is very similar to ZrO2; the powder preparation routes developed for ZrO2 ceramics are equally applicable to HfO, ceramics. Cubic HfO2 stabilized by yttrium oxide was prepared at low temperature (<1000 deg rees C) by oxalic precursors pyrolysis or via molten salts reaction. T he powders obtained were characterized by X-ray diffraction, granular distribution, and transmission electron microscopy. TEM has been prove d to be the best technique to characterize the powder size homogeneity , chemical composition, and crystallographic structure. (C) 1995 Acade mic Press, Inc.
