Summary: | PROBLEM TO BE SOLVED: To provide a barium titanate powder which has a particle diameter in the solid phase method capable of being controlled ≥300 nm, and uniform particle shapes, low-defective high-crystallinity, high dispersibility and low intraparticle porosity, and a narrow particle size distribution containing no ultrafine particle; and to provide a method for manufacturing a barium titanate powder, and a ceramic electronic component using the same.SOLUTION: The barium titanate powder has a perovskite structure, a rectangular parallelpiped or a rectangular parallelpiped-analogous shape, and a specific surface area measured by BET method of ≤3.2 m/g. The barium titanate powder has high crystallinity, high dispersibility, few defects, narrow particle size distribution and low intraparticle porosity and uniform particle shapes. |
