FERRITE POWDER FOR BONDED MAGNET AND BONDED MAGNET USING THEREOF

摘要

PROBLEM TO BE SOLVED: To provide magnet plumbite type ferrite powder with which a bonded magnet, having the maximum energy product (BH) max of specific value or higher, can be obtained. SOLUTION: This ferrite powder is the magnet plumbite type ferrite powder for a bonded magnet having the average particle diameter of 0.9 to 1.5μm, the compression density when compressed at the pressure of 1 ton/cm<2> is 3.40g/cm<3> or higher, the melt flow rate is 7g/10min or higher, and the powder PH when measured by JIS-K5101 is 7 to 10.
