  • Patent number: 8764913
    Abstract: Surface-coated metal nanoparticles comprising: metal nanoparticles having an average particle diameter of 1 to 100 nm, and an organic coating film provided on a surface of each of the metal nanoparticles, wherein the organic coating film comprises a fatty acid having 8 or more carbon atoms and an aliphatic amine having 8 or more carbon atoms, and a molar ratio of the aliphatic amine to the fatty acid is aliphatic amine/fatty acid from 0.001/1 to 0.2/1.
    Type: Grant
    Filed: August 17, 2011
    Date of Patent: July 1, 2014

  • Patent number: 8497022
    Abstract: Provided is a composite nanometal paste which, when a layer of the paste interposed between upper and lower bodies is sintered in an inert gas under no load until the layer turns to a metal layer, attains a shear bond strength between the upper and lower bodies of 10 MPa or higher. The composite nanometal paste contains, as metallic components, composite metallic nanoparticles comprising metal cores with an average particle diameter of X (nm) and an organic coating layer formed around the circumference, metallic nanofiller particles having an average particle diameter of d (nm), and metallic filler particles having an average particle diameter of D (nm), and satisfies the first relation X<d<D and the second relation X<d<100 (nm).
