Yttrium‐doped alumoxanes are demonstrated to be ideal precursors for ternary aluminum oxides such as yttrium aluminum garnet (YAG). The yttrium‐doped alumoxanes (see Figure), formed by the reaction of carboxylate alumoxanes with Y(acac) 3 (acac = acetylacetonate), provide a chimie douce route to YAG that directly competes with the traditional sol‐gel synthesis and has the additional advantage of greater processability of the pre‐ceramic.
