  • Conductive adhesive agent with ultrafine particles
    Patent number: 7262511
    Abstract: The present invention provides a conductive adhesive agent capable of being diluted with a solvent to give good coating workability and allowing formation of a conductive joint excellent in both thermal conductivity and electrical conductivity by inhibiting a gas generated when a binder resin is heat-cured after attachment of a part. The conductive adhesive agent according to the present invention is a conductive adhesive agent wherein, based on 100 parts by weight of silver powder having an average particle diameter of micrometers, which is used for a conductive medium, e.g.

  • Production method of gas sensor
    Patent number: 7070829
    Abstract: To provide a method for producing a sensing film for gas sensors by sintering particles comprising a metal or a metal oxide on a substrate, where the sensing film for gas sensors having excellent sensor properties such as sensitivity and responsibility can be easily and simply formed. A nano-meter order particle (100), a dispersant (110) for preventing aggregation of the particles (100), and a scavenger (120) for trapping the dispersant (110) at the sintering are mixed in a solvent (130) to prepare a paste body (140), and this paste body (140) is coated on a base material and fired, thereby forming a sensing film.
