Synthesis of nanocrystalline ytterbium modified PbTiO3

摘要

Ytterbium (Yb) modified lead titanate ceramics (Pb1-xYbx TiO3, with x = 0.05) (PYbT) were prepared by the Pechini method. The materials were calcinated under flowing oxygen at different temperatures from 300degreesC to 700degreesC. Nanostructured PYbT was obtained by high-energy milling and investigated using X-ray diffraction (XRD), thermogravimetric analysis (TGA), differential thermal analysis (DTA), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and surface area analysis (BET). The results revealed that the obtained materials are formed by nanometric particles. (C) 2003 Elsevier Inc. All rights reserved.
