Two different specific surface area of starting BaCO3, 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.
