Abstract
The fine barium titanate particles of the present invention have an average primary particle diameter of from 10 nm to less than 20 nm, a sphericity of 1.00 to 1.18, and a ratio of an average secondary particle diameter to the average primary particle diameter of 0.7 to 6.0. The fine barium titanate particles of the present invention can exhibit a small behavior particle diameter and can be readily monodispersed notwithstanding very fine particles, and as a result, can be suitably used as various dielectric materials because the particles are free from aggregation therebetween and have an excellent dispersibility.
