Abstract: A magnetic powder contains at least the first alloy powder and the second alloy powder in which those composition are different. The second alloy powder has a smaller median diameter than the first alloy powder and contains Cr of 0.3-14 at %. The first alloy powder has a Cr content of 0.3 at % or less. With respect to the total sum of the first alloy powder and the second alloy powder, a content of the second alloy powder is 20-50 vol % and the ratio of the median diameter of the first alloy powder to the second alloy powder is 4-20. The first alloy powder comprises either an amorphous phase or a crystalline phase having an average crystallite size of 50 nm or smaller. Thereby, a magnetic powder having low magnetic loss and good corrosion resistance without damaging insulation resistance and saturation magnetic flux density can be realized.

Abstract: A method for recovering metal values from a molten slag composition includes atomizing the slag with an oxygen-containing gas in a gas atomization apparatus, to produce solid slag granules. Oxygen in the atomizing gas converts metals to magnetic metal compounds, thereby magnetizing the metal-containing slag granules. These metal-containing slag granules are then magnetically separated. Larger amounts of metals may be removed by passing the molten slag through a pre-settling pan with an adjustable base, and/or discontinuing atomization where the metal content of the slag exceeds a predetermined amount. Solid slag granules produced by atomization may be charged to a recovery unit for recovery of one or more metal by-products. An apparatus for recovering metal values from molten slag includes a gas atomization apparatus, a flow control device for controlling the flow of atomizing gas, a control system, and one or more sensors to detect metal values in the slag.

Abstract: A magnetic powder is represented by general formula Fea(SibBcPd)100-a, and is produced with a gas atomization method. When the value of a and the value of b in the general formula is represented (a, b), (a, b) is within a predetermined region V1. Similarly, (a, c) and (a, d) are within a predetermined region, respectively. Whereby, it is possible to obtain an alloy magnetic powder which has high saturation magnetic flux density, low magnetic loss, and is spherical and easy to handle; and a magnetic core, a variety of coil components, and a motor can be realized by using the magnetic material.
