Title:
FERRITE PARTICLES, RESIN COMPOSITION, AND RESIN FILM
Document Type and Number:
WIPO Patent Application WO/2017/169316
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: ferrite particles that have a high saturation magnetization and excellent dispersibility in resins, solutions, or resin compositions; a resin composition that includes the ferrite particles; and a resin film comprising the resin composition. The ferrite particles are single crystals having an average particle size of 1 to 2000 nm, are Mn ferrite particles having a spherical particle shape, and have a saturation magnetization of 45 to 95 Am2/kg. The resin composition includes the ferrite particles as a filler. The resin film comprises the resin composition.
