Title: NI-ZN-CU FERRITE PARTICLES, RESIN COMPOSITION AND RESIN MOLDED BODY
Abstract:
The purpose of the present invention is to provide: ferrite particles which have high saturation magnetization and high electrical resistivity, while exhibiting excellent dispersibility with respect to resins, solvents or resin compositions; a resin composition which contains the ferrite particles; and a resin molded body which is formed from this resin composition. Ni-Zn-Cu ferrite particles according to the present invention are characterized by: being single crystal particles having an average particle diameter of 1-2,000 nm; having a polyhedral particle shape; and containing 5-10% by weight of Ni, 15-30% by weight of Zn, 1-5% by weight of Cu and 25-50% by weight of Fe.
