摘要：

Nanocrystalline zirconia with a grain size of similar to5 run was surface-doped with 3 and 30 mol% alumina by chemical vapor synthesis using two sequential hot-wall reactors. The powders were characterized by high-resolution transmission electron microscopy, X-ray diffractometry (XRD), and nitrogen adsorption. Aqueous dispersions were studied by zeta-potential measurements and photocorrelation spectroscopy. Green and sintered ceramic bodies were investigated by high-resolution scanning electron microscopy, XRD, and nitrogen adsorption. Zirconia surface-doped with 3 mol% of alumina displays substantial changes in dispersability and sinterability compared with pure nanocrystalline zirconia.
