Title:
METALLIC MAGNETIC POWDER CONTAINING COBALT
Document Type and Number:
Japanese Patent JPS5844701
Kind Code:
A
Abstract:
PURPOSE: To obtain the magnetic powder, form thereof is excellently maintained, by adsorbing Mo to the metallic magnetic powder containing Co and treating the powder.
CONSTITUTION: Mo Is adsorbed previously to the metallic magnetic powder containing Co, and the powder is reduced, and the magnetic metallic powder is obtained. Consequently, the change of the form of the powder due to sintering being generated in the powder and the growing of the powder and the like are inhibited superiorly when the minute magnetic powder oxidized is reduced, and the form of grains can be kept. Accordingly, the metallic powder containing Co, which has desired magnetic characteristics, can easily be obtained.
