Abstract: In the present invention, a molding material which is a mixture of a metal powder and a binder is melted and injection molded (primary molding) into an injection mold, thereby creating an injection molded body 10A, 110A, 210A, 310A, 410A, 610A or an intermediated molded body 10C, 310C, 410C, 610C. The created injection molded body or intermediate molded body is placed in a transfer mold 30, 130, 230, 330, 430, 630 and subjected to gravity casting (secondary molding) which causes deformation. A sintered body 10E, 110E, 210E, 310E, 410E, 610E is produced through degreasing and sintering of the injection molded body 10A, 110A, 210A, 310A, 410A, 610A.

Abstract: The present invention provides a powder for a magnetic member being excellent in moldability and difficult to oxidize, a powder compact produced from the powder, and a magnetic member suitable for a raw material of a magnetic member such as a rare earth magnet. A powder for a magnetic member includes magnetic particles 1 which constitute the powder for a magnetic member and each of which is composed of less than 40% by volume of a hydrogen compound 3 of a rare earth element, and the balance composed of an iron-containing material 2 which contains iron and an iron-boron alloy containing iron and boron. The hydrogen compound 3 of a rare earth element is dispersed in a phase of the iron-containing material 2. An antioxidant layer 4 having a low-oxygen permeability coefficient is provided on the surface of each of the magnetic particles 1. Since the phase of the iron-containing material 2 is uniformly present in each of the magnetic particles 1, the powder has excellent moldability and the density of a powder compact can be easily increased. By providing the antioxidant layer 4, oxidation of a newly formed surface formed on each of the magnetic particle 1 during molding is little oxidized, and a decrease in a magnetic phase ratio due to the presence of an oxide can be suppressed.
