PURPOSE:To manufacture a ferrite magnet having both high remanent flux density and coersive force by a method wherein the slurry containing ferrite particles in the basic composition of Mo.nFe2O3 with polycarboxylic acid base dispersing agent added thereto is compression molded in a magnetic field to be sintered later. CONSTITUTION:Polycarboxylic acid dispersing agnet as well as ammonium bicarbonate for avoiding the electrical neutralization therewith are added to a slurry containing ferrite particles in basic composition of Mo.nFe2O3 (M: includes one kind or more out of Ba, Sr, Pb, n=5-6) to be compression molded in a magnetic field and then sintered. Through these procedures, the dispersibility of the ferrite particles in the slurry can be enhanced thereby enabling the ferrite magnet having excellent magnetic characteristics to be manufactured. |
