An inorganic structure body has a free-standing structure including a fibrous member and/or a shell. The fibrous member and/or the shell include a metal and/or an inorganic material and have a three-dimensionally continuous configuration. The free-standing structure may have a structure that is based on a nonwoven fabric or a porous membrane used as a substrate.

Inorganic structure body, device, and method for manufacturing inorganic structure body

An oxide ion conductor has a XZ(TO)structure, where X is a divalent metal element, Z is a trivalent metal element, and T is a tetravalent metal element, and has a composition expressed by (XA)(ZB)(TC)Owhere the element X is Ca, Fe, Gd, Ba, Sr, Mn, and/or Mg, the element Z is Al, Cr, Fe, Mn, V, Ga, Co, Ni, Ru, Rh, and/or Ir, the element T is Si and/or Ge, an element A is La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, and/or Sr, an element B is Zn, Mn, Co, Ru, and/or Rh, and an element C is Si, Al, Ga, and/or Sn, 0&#x2264;x&#x2264;0.2, 0&#x2264;y&#x2264;0.2, and 0&#x2264;z&#x2264;0.2 are satisfied, and &#x3b4; is a value securing electrical neutrality.

Oxide ion conductor and electrochemical device

A powder magnetic core having excellent specific resistance or strength. The powder magnetic core has soft magnetic particles, first coating layers that coat the surfaces of the soft magnetic particles and include aluminum nitride, and second coating layers that coat at least a part of the surfaces of the first coating layers and include a low-melting-point glass having a softening point lower than an annealing temperature for the soft magnetic particles. The first coating layers including aluminum nitride are excellent in the wettability to the low-melting-point glass which constitutes the second coating layers and suppress diffusion of constitutional elements between the soft magnetic particles and the low-melting-point glass of the second coating layers. The powder magnetic core can stably exhibit a higher specific resistance and higher strength than the prior art owing to such a synergistic action of the first coating layers and second coating layers.

Powder magnetic core, powder for magnetic cores, and methods of manufacturing them

A powder for a powder magnetic core, a powder magnetic core, and methods of producing those products are provided, so that mechanical strength of a powder magnetic core can be enhanced by hydrosilylation reaction between vinylsilane and hydrosilane without degrading magnetic properties. The powder for a powder magnetic core is composed of magnetic particleshaving a surfacecoated with an insulating layer, wherein the insulating layerincludes a polymer resin insulating layercomprising vinylsilaneand hydrosilane.

Powder for powder magnetic core, powder magnetic core, and methods for producing those products

An insulation film whose requisite constituent elements are first elements and a second element. The first elements include B, P, O and Fe. The second element can generate cations whose hexa-coordinated ion radius, defined by Shannon, R. D., is 0.073 nm or more, and which are bivalent or more. Since the second element having a large ion radius is incorporated into network formers made from the first elements, it is possible to improve the heat resistance of the insulation film.

The present invention is characterized in that, in a powder magnetic core obtained by compaction of an iron-based magnetic powder covered with an insulation film, a saturation magnetization Ms is Ms&#x2267;1.9 T in a 1.6 MA/m magnetic field; a specific resistance &#x3c1; is &#x3c1;&#x2267;1.5 &#x3bc;&#x3a9;m; a magnetic flux density Bis B&#x2267;1.1 T in a 2 kA/m magnetic field; and a magnetic flux density Bis B&#x2267;1.6 T in a 10 kA/m magnetic field. In accordance with the present invention, it has been possible to industrially carry out compacting iron-based magnetic powders under remarkably high compacting pressures. As a result, high-performance powder magnetic cores are obtained which have a high density, and which are good in terms of the specific resistance and magnetic permeability.
