Title:
POWDER AND DISPERSION OF FINE STRONTIUM TITANATE PARTICLES, AND RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/063281
Kind Code:
A1
Abstract:
The present invention relates to a powder composed of fine spherical strontium titanate particles, characterized by having an average primary-particle diameter of 50 nm or smaller, a roundness of 0.8 or greater, and a lattice constant of 3.925 Å or less. This finely particulate strontium titanate powder has high crystallinity, contains little water, and has a satisfactory particle size distribution. Composite films containing the particles evenly distributed therein can hence be provided without suffering any resin-film deterioration.
