    Abstract: A composite magnetic body used for a choke coil, etc. is formed by compression molding of a mixture of magnetic alloy powder containing iron (Fe) and nickel (Ni) as the main component, an insulating material and a binder of an acrylic resin. In the composite magnetic body, high packing rate of the magnetic alloy powder and good insulation between the powder particles stand together, exhibiting a low core loss and a high magnetic permeability. The composite magnetic body can be formed in various core pieces of complex shapes.

    Abstract: A non-aqueous electrolyte secondary battery containing an alloy particle capable of absorbing and desorbing lithium in the negative electrode has a short cycle life and is insufficient in high-rate discharge characteristics, since the alloy particle is pulverized during charge/discharge cycles. In order to solve this problem, a negative electrode is employed, which comprises an alloy particle containing: at least two selected from the group consisting of metal elements and semimetal elements; oxygen; and nitrogen. It is preferred that the alloy particle have a phase A capable of electrochemically absorbing and desorbing lithium ion and a phase B having lithium ion conductivity or lithium ion permeability and that the phase B contain larger amounts of oxygen and nitrogen than the phase A.

    Abstract: An alumina sintered body having a low dielectric loss tangent and a method for manufacturing the alumina sintered body are provided. An alumina sintered body contains Al2O3 99.50 mass % or more, and 99.95 mass % or less and sodium and silicon, wherein at a surface layer A in any given cross-section and a central portion B of the cross-section in a depth direction from the surface layer A, a concentration ratio of sodium to silicon in the surface layer A is smaller than the concentration ratio of sodium to silicon at the central portion B.
