    Abstract: Core-shell particles encapsulated by a thin film of a catalytically active metal are described. The particles are preferably nanoparticles comprising a non-noble core with a noble metal shell which preferably do not include Pt. The non-noble metal-noble metal core-shell nanoparticles are encapsulated by a catalytically active metal which is preferably Pt. The core-shell nanoparticles are preferably formed by prolonged elevated-temperature annealing of nanoparticle alloys in an inert environment. This causes the noble metal component to surface segregate and form an atomically thin shell. The Pt overlayer is formed by a process involving the underpotential deposition of a monolayer of a non-noble metal followed by immersion in a solution comprising a Pt salt. A thin Pt layer forms via the galvanic displacement of non-noble surface atoms by more noble Pt atoms in the salt. The overall process is a robust and cost-efficient method for forming Pt-coated non-noble metal-noble metal core-shell nanoparticles.

  • Patent number: 8961709
    Abstract: A solder paste using a Sn—Ag base, Sn—Cu base, or similar alloy powder has a high melting point, so it causes thermal damage to electronic devices. Sn—Ag—In base lead-free solder alloys having a low melting temperature have been studied, but they are difficult to use because they cause much occurrence of chips standing up during reflow. The present invention forms a solder paste by separating a Sn—Ag—In base lead-free solder into first and second solder alloy powders for which the difference in their peak temperatures measured by differential thermal analysis is at least 10° C. and blends the mixed powders with a flux.

  • Patent number: 8920580
    Abstract: In solder paste of the present invention, a first metal powder, a second metal powder, and a third metal powder are dispersed in a flux or a thermosetting resin. The first metal powder includes a first metal material such as Cu, Ag, Au, or Pd that serves as a base metal. A second metal material such as Sn or In that has a melting point lower than that of the first metal material is coated on the surface of the first metal material. The second metal powder is made of a metal material such as Sn or In that has a melting point lower than that of the first metal material. The third metal powder such as a Cu, Ag, Au or Pd powder has an average particle diameter smaller than that of the first metal material and can form compounds with the second metal material and the second metal powder.

  • Patent number: 8911663
    Abstract: The present invention relates to ferromagnetic powders with an electrically insulating layer on iron particles intended for the manufacture of components having improved soft magnetic properties at low and medium frequencies. The invention comprises an iron powder coated with a dielectric insulating layer comprising boron bearing compounds to form an insulated ferromagnetic powder. The present invention also relates to a method of making these insulated ferromagnetic powders. The present invention further relates to a method of synthesizing a product made from insulated ferromagnetic powders via a post-heat treatment at a moderate temperature (300° C. to 700° C.), to form a glass-like coating which acts as an electrical insulator. A preferred embodiment of the present invention is obtained when small amounts of alkali bearing compounds are added to the precursors to modify the coating chemistry and significantly increase the electrical resistivity after heat treatment.

  • Patent number: 8834747
    Abstract: Compositions containing tin nanoparticles and electrically conductive particles are described herein. The tin nanoparticles can have a size below about 25 nm so as to make the compositions fusable at temperatures below that of bulk tin (m.p.=232° C.). Particularly, when the tin nanoparticles are less than about 10 nm in size, the compositions can have a fusion temperature of less than about 200° C. The compositions can contain a whisker suppressant to inhibit or substantially minimize the formation of tin whiskers after tin nanoparticle fusion. In some embodiments, the compositions contain tin nanoparticles, electrically conductive particles comprising copper particles, and a whisker suppressant comprising nickel particles. Methods for using the present compositions are also described herein. The present compositions can be used as a lead solder replacement that allows rework to be performed.
