Abstract
A method for producing rare-earth magnets is provided in which, when a slurryhaving a rare-earth-compound powder dispersed therein is applied to sintered magnet bodiesand dried to apply the powder thereto, the magnet bodiesare accommodated and conveyed in holding pocketsof a conveyance drumwhich rotates in a state of being partially immersed in the slurry, and, as a result, the magnet bodiesare immersed in the slurry, withdrawn from the slurry, and dried to apply the powder to the sintered magnet bodies. According to this production method, the powder can be uniformly and efficiently applied, wastage of the rare-earth compound can be effectively suppressed, and a reduction in the surface area of equipment for performing an application step can also be achieved.
