Abstract

PURPOSE: To obtain metallic magnetic powder with superior magnetic characteristics by simultaneously sticking a Zn compound and an Si compound to powder of a metallic compound consisting essentially of iron oxyhydroxide or iron oxide, granulating the powder, and carrying out reduction under heating.
CONSTITUTION: A Zn compound and an Si compound are simultaneously stuck to the particle surfaces of powder of a metallic compound consisting essentially of iron oxyhydroxide or iron oxide. The powder is granulated into lumps and reduced under heating at about 300W600°C in a reducing gaseous atmosphere of gaseous hydrogen or the like. By this method the reduction under heating can be carried out sufficiently and uniformly while effectively inhibiting sintering among the granules and the particles of the powder and the deformation of the particles. As a result, iron-base metallic magnetic powder with superior magnetic characteristics is obtd.
