Methods for forming inorganic compound oxides are described herein. Such methods include combining, at a substantially constant pH of between about 5 and about 6.75, over a period of at least about 5 minutes, an acidic precursor composition and a basic composition to form a precipitate composition, in which the acid precursor composition comprises an alumina precursor, an ceria precursor, a zirconia precursor and optionally one or more dopant precursors; stabilize the precipitate by increasing the pH of the precipitate composition to between about 8 and about 10; and calcining the stabilized precipitate to form an inorganic compound oxide. Inorganic compound oxides formed using such methods are also described. |
