Abstract
PURPOSE: To easily and economically produce the titled powder suitable as a sintered magnet, etc. by mixing a flux comprising halogenides of Ba, Sr and Pb to composite ferrite particles consisting of two or more kinds of amorphous said elements and by sintering said mixed materials.
CONSTITUTION: The composite ferrite particle powder expressed by the formula Mo.nFe2O3 (M is two or more kinds out of Ba, Sr and Pb, n=5W6, respectively) consisting of two or more kinds of the amorphous Ba, Sr and Pb obtainable by a dry method is prepared. Next, one or more kinds out of Ba or Sr chloride or fluoride, or bromide, iodide or oxide of Pb, for example BaCl2 or SrCl2 is mixed at 5W90wt% as a flux into this ferrite particle powder. Thence, this mixture is sintered by being heated to the temp. above the co-m.p. of the flux and below 1,400°C, whereby the intended hexagonal-platelike composite ferrite particle powder is produced.
