Title:
ボンド磁石用フェライト粒子粉末、ボンド磁石用樹脂組成物ならびにそれらを用いた成型体
Document Type and Number:
Japanese Patent JP5393989
Kind Code:
B2
Abstract:
The present invention relates to ferrite particles for bonded magnet, having a volume-average particle diameter of 2.1 to 2.7 µm and a particle diameter x90 of 4.3 to 5.4 µm wherein the x90 represents a particle diameter at which a cumulative percentage of particles under sieve (undersize particles) based on a volume thereof is 90%, when determined from a particle size distribution thereof measured by using a laser diffraction type particle size distribution measuring apparatus.
