摘要：
Barium titanate (BaTiO3) particles were homogeneously coated with yttrium compound by the decomposition of yttrium nitrate with urea in aqueous solution. The morphologies of the yttrium compound-coated BaTiO3 particles were controlled by varying the initial concentration of yttrium nitrate for a fixed reaction temperature and time. The relationship between the initial yttrium concentration and the coating layer thickness was confirmed by transmission electron microscopy (TEM) images. Electron probe microanalyzer (EPMA) and XRD data showed that the BaTiO3 particles were homogeneously coated with yttrium compound.
