Title:
SOFT MAGNETIC METAL POWDER, SOFT MAGNETIC METAL FIRED BODY, AND COIL-TYPE ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2021/060479
Kind Code:
A1
Abstract:
[Problem] To provide a soft magnetic metal powder or the like from which a soft magnetic metal fired body can be provided which has a high magnetic permeability μ and a specific resistance ρ and is contained in a coil-type electronic component having sufficiently high inductance L and Q value and unlikely to be plating-extended and short-circuited. [Solution] Provided is a soft magnetic metal powder containing soft magnetic metal particles containing at least Fe and Ni. Said soft magnetic metal powder further contains P, Si, Cr and/or M. M is at least one selected from among B, Co, Mn, Ti, Zr, Hf, Nb, Ta, Mo, Mg, Ca, Sr, Ba, Zn, Al, and rare earth elements. The content of each element is within a predetermined range.
