摘要:
To provide a hexagonal type barium titanate powder having a fine and uniform particle size and contributing to a thinner dielectric layer. A hexagonal type barium titanate powder according to the present invention has the following characteristics that a maximum particle diameter is 1.0 μm or less, a ratio of 90% accumulated particle diameter and 50% accumulated particle diameter is 3.0 or less, and a hexagonal ratio is 50% or more.
