Title:
チタン酸バリウム粒子粉末、該粉末を含有する分散体及び塗膜
Document Type and Number:
Japanese Patent JP6825556
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a barium titanate particle powder having high transparency when made into a film due to fineness thereof, a sharp particle size distribution, and little elution of Ba ion which inhibits dispersion. Barium titanate particle powder having a primary particle average particle diameter of 10-60 nm, a particle coefficient of variation (standard deviation of particle size distribution divided by average particle diameter) of 0.35 or less, and 1,000 ppm or less of Ba ion eluted from the powder into an aqueous solvent, and a dispersion and coating film containing the barium titanate particle powder.
