The role of individual steps in dewatering of the yttrium hydroxynitrate precipitate by organic liquids in relation to powder morphology and sinterability of the oxide is studied. It was found that washing of the precipitate with toluene results in one or two orders of magnitude reduction in the particle size. A mechanism was offered for the effect of toluene wash. Variation of electrical double layer potential as a function of distance for different liquids is constructed to explain the effects of acetone-toluene-acetone treatment on the particle size and sinterability of the precursor.
