摘要

BaTi_(0.87)Sn_(0.13)O_3 (BTS_(13)) nanopowder was prepared by low-temperature aqueous synthesis (LTAS) method. The evolution of the structure and microstructure of the precursor precipitate, heated at temperatures up to 1000°C was studied by TGA, FT-IR, SEM and XRD techniques. The dried precipitate showed a microstructure consisting of nano-sized grains (~40 nm) with great tendency to agglomeration. BaTi_(0.87)Sn_(0.13)O_3 single phase was obtained at 800 °C. The ceramics prepared from as-obtained BTS_(13) powders (60-70 nm) show good dielectric and ferroelectric characteristics.
