Popis:	BaTiO 3 powders were prepared according to a novel fabrication route. Submicrometric TiO 2 particles were coated by BaCO 3 nanoparticles which are precipitated by urea decomposition method. Under suitable operation conditions, homogeneous core–shell TiO 2 @BaCO 3 structure, an optimal BaCO 3 precipitation yield and stoichiometry control was achieved. BaTiO 3 particles were successfully obtained after heat treatment at 1000 °C for 1 h. The size of the obtained particle was about 150–200 nm, in agreement with the original size of the TiO 2 core.
