摘要

Two different specific surface area of starting BaCO_3, 10 and 30 m²/g, are used to prepare solid-state BaTiO₃ powder. Pure tetragonal BaTiO₃ was obtained at a lower calcination temperature with smaller BaCO₃, and the kinetic calculations of activation energy also agree with it. A clear, thin, and nano-sized cubic BaTiO₃ clusters on TiO₂ particles were also observed. A narrower particle size distribution of BaTiO₃ powder (350 nm) was obtained from 30 m²/g of starting BaCO₃ at 1000°C. After sintering with reducing atmosphere, the ceramics with potential of X8R or X7R specifications and a clear core–shell microstructure were obtained in this study.
