摘要：
A zirconia-containing composition and processes for synthesizing same. The composition comprises least about 99.9 percent tetragonal phase zirconia, based on the total crystalline zirconia in the zirconia-containing composition as determined by x-ray diffraction (XRD). The composition also has a substantially spherical morphology and comprises less than 100 wppm chlorine, based on the total weight of the zirconia-containing composition. The zirconia-containing composition has an average surface area of at least 80 m2/g and an average particle size of less than about 10 microns.
