    Abstract: A flat soft magnetic metal powder is provided that includes: Ni in the range of 60 to 90 mass %, one or more kinds of Nb, V, and Ta in the range of 0.05 to 20 mass % in total (0.05 to 19.95 mass % when Mo is added thereto), Mo in the range of 0.05 to 10 mass % if necessary, one or two kinds of Al and Mn in the range of 0.01 to 1 mass % in total if necessary, and the balance including Fe; an average grain size of 30 to 150 μm and an aspect ratio (average grain size/average thickness) of 5 to 500; and a flat face. Here, with a peak intensity of a face index (220) in an X-ray diffraction pattern I220 and a peak intensity of a face index (111) I111, a peak intensity ratio I220/I111 is in the range of 0.1 to 10.

    Abstract: Glycerol is used as a solvent medium for the precipitation of a complex of nickel and glycerol material. The precipitate is separated from the liquid solvent and dried and calcined in air to produce small (nanometer size) particles characterized by a nickel core encased in a nickel oxide shell. The proportions of nickel core and nickel oxide shell can be controlled by management of the time and temperature of heating in air. Prolonged heating in air can produce nickel oxide particles, or calcining of the precipitate in nitrogen produces nickel particles.

    Abstract: The present invention refers to a process for production of a powder of niobium and/or tantalum having high purity, large specific surface area, controlled contents of oxygen and nitrogen, and a morphology that is adequate for use in the manufacture of capacitors, characterized by including one sole step of reduction of a controlled layer of niobium and/or tantalum oxide (NbxOy, and/or TaxOy, where x=1 to 2 and y=1 to 5) deliberately formed over particles of metallic niobium and/or tantalum and/or hydrides thereof of adequate purity, by alkali metals or earth alkali metals and/or hydrides thereof in a bath of molten salts followed by a step of dissolution of the salt in an aqueous solution for recovery of the niobium and/or tantalum powder. These particles produced using the said process have a small size, large surface area and a sponge-like morphology, being thereby adequate for the production of capacitors.

    Abstract: A method of producing an FeCrAl material by gas atomization, wherein in addition to containing iron (Fe), chromium (Cr) and aluminium (Al) the material also contains minor fractions of one or more of the materials molybdenum (Mo), hafnium (Hf), zirconium (Zr), yttrium (Y), nitrogen (N), carbon (C) and oxygen (O). The invention is characterized by causing the smelt to be atomized to contain 0.05-0.50 percent by weight tantalum (Ta) and, at the same time, less than 0.10 percent by weight titanium (Ti). According to one highly preferred embodiment, nitrogen gas (N2) is used as an atomizing gas to which a given amount of oxygen gas (O2) is added, said amount of oxygen gas being such as to cause the atomized powder to contain 0.02-0.10 percent by weight oxygen (O) at the same time as the nitrogen content of the powder is 0.01-0.06 percent by weight. The invention also relates to a high temperature material.
