Title:
BARIUM TITANATE PARTICULATE POWDER AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/190452
Kind Code:
A1
Abstract:
[Problem] To provide: a barium titanate particulate powder which is fine and highly crystalline, can be suitably used as a raw material for a small-sized, high-performance electronic component or optical component due to the easy dispersion properties thereof in both an aqueous solvent and a non-aqueous solvent, and can also be suitably used for MLCC due to the low ignition loss thereof; and a production method therefor. [Solution] The barium titanate particulate powder has an average primary particle diameter of 20 nm to 150 nm, wherein a value of D95/D50 is 5 or less, where D50 is a diameter of aggregated particles in an aqueous solvent corresponding to 50% of the cumulative frequency distribution and D95 is a diameter corresponding to 95% of the cumulative frequency distribution, and the maximum torque of oil absorption characteristics is 0.2 N·m or less.
