Abstract

Nanoparticles of CeO₂ doped with 10 mol% Dy₂O₃ have been synthesized via a homogeneous precipitation method, employing nitrates as the starting salts and hexamethylenetetramine (HMT) as the precipitant, which was achieved under ambient pressure and hydrothermal conditions, respectively. Characterizations of the powders were made by elemental analysis, differential thermal analysis/thermogravimetry (DTA/TG), X-ray diffractometry (XRD) and field-emission scanning electron microscopy (FESEM). The results show that an additional hydrothermal treatment affects significantly the powder properties, and well dispersed, nanocrystalline solid solution with expected dopant content was obtained under the reaction conditions.
