Title:
FERRITE POWDER, RESIN COMPOSITION, AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2017/170426
Kind Code:
A1
Abstract:
The ferrite powder of the present invention can be detected by a metal detector, and is characterized by including hard ferrite grains,and having 1 ppm to 200 ppm, inclusive, of Na as measured using ion chromatography. The grains that constitute the ferrite powder preferably have a volume median particle diameter of 0.1 μm to 100 μm, inclusive. The residual magnetism, as measured using a VSM when a magnetic field of 10K·1000/4πA/m is applied, is preferably 25A·m2/kg to 40A·m2/kg, inclusive.
