| 简介 |
Provided is a method for producing a rare earth sintered magnet using granules having excellent fluidity, which cannot only improve dimensional accuracy of a compact, but also improves productivity, without causing properties to dramatically drop. This is a method for producing a raw material powder for a rare earth sintered magnet, characterized by comprising the steps of : obtaining a mixture by adding an organic liquid to primary alloy particles having a predetermined composition; and producing granules having the primary alloy particles adhered together by the organic liquid from the mixture. In the present invention, it is preferable to add from 1.5 to 15.0% by weight of the organic liquid to the primary alloy particles. This is because if less than 1.5% by weight, in some cases it is difficult to efficiently produce the granules, while if more than 15.0% by weight, moisture is excessive, whereby it is sometimes necessary to remove the unnecessary moisture in order to carry out suitable compacting in a magnetic field. |
