Title:
FERRITE RESIN
Document Type and Number:
Japanese Patent JP3521467
Kind Code:
B2
Abstract:
PURPOSE: To obtain ferrite resin having high permeability and high Curie point by using ferrite powder in which B2O3, Sb2O3, Bi2O3 is added to the powder containing a raw material composition of a predetermined range of a ternary composition diagram of Fe2O3, ZoO and (NiO+CuO).
CONSTITUTION: Ferrite resin comprises 60vol.% or more of Ni-Cu-Zn ferrite powder containing 4mol% or more of NiO and CuO and a raw material composition of a range surrounded by six points of A, B, C, D, E and F in a ternary composition diagram of Fe2O3, Zn0 and (NiO+CuO) to be kneaded with resin and further containing at least one selected from B2O3 (0.1-2wt.% of content), Sb2O3 (0.1-2wt.% of content) and Bi2O3 (0.01-0.2wt.% of content).
