NICKEL-ZINC-COPPER BASED FERRITE PARTICLE, RESIN COMPOSITION, AND RESIN MOLD

摘要

PROBLEM TO BE SOLVED: To provide: ferrite particles high in saturation magnetization and electric resistance, and superior in dispersibility in a resin, a solvent or a resin composition; a resin composition including the ferrite particles; and a resin mold arranged by use of the resin composition.SOLUTION: A Ni-Zn-Cu based ferrite particle comprises a single crystal material having an average particle diameter of 1-2000 nm, and has a polyhedral particle shape. The Ni-Zn-Cu based ferrite particle includes: 5-10 wt.% of Ni; 15-30 wt.% of Zn; 1-5 wt.% of Cu; and 25-50 wt.% of Fe.SELECTED DRAWING: Figure 1
