Title:
METHOD FOR PRODUCING SOFT MAGNETIC COMPACT
Document Type and Number:
Japanese Patent JP2007211299
Kind Code:
A
Abstract:

To provide a green compact of ferrite-coated soft magnetic grains whose direct current superposition properties are improved.

Regarding the method for producing a soft magnetic compact using ferrite-coated soft magnetic grains in which ferrite plating is applied to the surface of each soft magnetic grain grain, the ferrite-plated soft magnetic grains are heat-treated in an oxygen-containing atmosphere, and are thereafter subjected to green compacting and heat treatment after the compacting.
