The effect of agglomerate strength on sintered density was determined for several yttria powders made by intentionally agglomerating 0.1-..mu..m, monodisperse yttriuim hydrocarbonate precursor spheres and calcining separate portions of the precursor at different temperatures to vary the strength of the intraaglomeate bonds. In this way, the effects of differences in particle morphology and other characteristics among the powders were minimized and the effect of agglomerate strength could be seen more clearly.
