摘要：

BaTiO3 powders were prepared according to a novel fabrication route. Submicrometric TiO2 particles were coated by BaCO3 nanoparticles which are precipitated by urea decomposition method. Under suitable operation conditions, homogeneous core-shell TiO2@BaCO3 structure, an optimal BaCO3 precipitation yield and stoichiometry control was achieved. BaTiO3 particles were successfully obtained after heat treatment at 1000 degrees C for 1 h. The size of the obtained particle was about 150-200 nm, in agreement with the original size of the TiO2 core. (C) 2010 Elsevier B.V. All rights reserved.
