  • Publication number: 20140295178
    Abstract: Provided is a process for producing satisfactory particles held in porous silica. The process comprises (a) the step of preparing porous silica, (b) the step of bringing the porous silica into contact with a liquid which contains either a metal or a compound that has the metal as a component element and infiltrating the liquid into the pores of the porous silica, and (c) the step of subjecting, after the step (b), the impregnated porous silica to a heat treatment to thereby form fine particles comprising the metal or the metal compound in the pores of the porous silica. When porous silica is synthesized by hydrolyzing an alkoxysilane in a solvent-free system, it is possible to synthesize porous silica having a fine pore diameter. Use of this porous silica as a template facilitates formation of particles (e.g., W, Cu, Cr, Mn, Fe, Co, or Ni or an oxide of any of these metals) that show peculiar properties not observed in the bulk material.

Metal parts coated with the coating compositions have very satisfactory properties such as heat and corrosion resistance.

  • Patent number: 7704909
    Abstract: An electrode for hydrogen generation can maintain a low hydrogen overvoltage for a long period of time even when electrolysis is conducted there not only with a low current density but also with a high current density. The electrode for hydrogen generation has a coating layer formed on a conductive base member by applying a material not containing any chlorine atom prepared by dissolving lanthanum carboxylate in a nitric acid solution of ruthenium nitrate and thermally decomposing the material in an oxygen-containing atmosphere.

  • Publication number: 20100092682
    Abstract: A method for fabricating a thermal optical heating element capable of adjusting refractive index of an optical waveguide is disclosed. A silicon block is initially formed on a cladding layer on a silicon substrate. The silicon block is located in close proximity to an optical waveguide. A cobalt layer is deposited on the silicon block. The silicon block is then annealed to cause the cobalt layer to react with the silicon block to form a cobalt silicide layer. The silicon block is again annealed to cause the cobalt silicide layer to transform into a cobalt di-silicide layer.

  • Patent number: 7678449
    Abstract: Iridescent magnetic pigments are produced by depositing a ferrite layer and a second metal oxide layer in succession on a substrate. The substrate may be platy and is coated with the ferrite, which is then coated with the second metal oxide layer to provide interference color effect. At least one of the layers is magnetic. The magnetic pigment may be used in coatings such as paints.

  • Publication number: 20100015468
    Abstract: A method for manufacturing metallized aluminum nitride substrate. The method includes: Step A for forming a high-melting point metal layer over a sintered aluminum nitride substrate; Step B for forming over the high-melting point metal layer an intermediate metal layer of at least one selected from the group of: nickel, copper, copper-silver, copper-tin, and gold by plate processing; and Step C for forming a surface metal layer containing silver as a main component over the intermediate metal layer by coating a silver paste whose glass component content is 1 mass % or less and firing under nonoxidizing atmosphere. By this method, it is capable of forming a glass component-free silver layer which is adhered at a high degree of adhesion strength onto the high-melting point metal layer formed over the aluminum nitride substrate as a top face by thick-film method using a silver paste which makes thick-membrane forming easier.

  • Publication number: 20090162557
    Abstract: A paste including metal or metal alloy particles (which are preferably silver or silver alloy), a dispersant material, and a binder is used to form an electrical, mechanical or thermal interconnect between a device and a substrate. By using nanoscale particles (i.e., those which are less than 500 nm in size and most preferably less than 100 nm in size), the metal or metal alloy particles can be sintered at a low temperature to form a metal or metal alloy layer which is desired to allow good electrical, thermal and mechanical bonding, yet the metal or metal alloy layer can enable usage at a high temperature such as would be desired for SiC, GaN, or diamond (e.g., wide bandgap devices). Furthermore, significant application of pressure to form the densified layers is not required, as would be the case with micrometer sized particles.
