Abstract
PURPOSE: To provided desired characteristics to an end product (ferrite magnet) by controlling a precalcining process so that the amplified relative value of permeability of pellets becomes a predetermined value.
CONSTITUTION: During manufacture of a hexagonal system ferrite magnet according to the processes about by the table, the amplified relative value [Pμ] (value obtd. by amplifying permeability by certain times) of permeability of precalcined pellets is measured, and by precalcining the pellets in the precalcining process (3) so that the value becomes a predetermined value, the characteristics of the end product are controlled. For example, a significant positive correlation is present between [Pμ] and the residual magnetic flux density [Br] of the product magnet, so that [Pμ] value corresponding to a desired [Br] value is calculated beforehand in accordance with a regression equation between the values formed separately, and the pellets are precalcined so as to satify the [Pμ] value in the precalcining process.
