| 摘要 |
The present invention is directed to a method for a continuous mass-production, on an industrial scale at a high efficiency, of magnetic metal particles having excellent magnetic properties by preventing particle deformation and mutual sintering of the particles in a reduction process, and/or by preventing deterioration of the magnetic properties and unevenness in the properties, particularly in the saturation magnetization, upon oxidation in a stabilization process. In this method, an iron compound based on iron oxyhydroxide can be thermally dehydrated in a thermal dehydration process. These processes can be conducted using apparatuses of the present invention which have a gas flow reactor (1); a belt conveyor being installed in the reactor and having a gas-passable belt (3) for transporting the material; a gas dispersion plate (2); and a heating means (4). <IMAGE> |
