    摘要： In sintering a metal powder after pressure molding into a given configuration, random amorphous flaky metal fine powders (10) are used as metal powder materials. In addition, spherical particulate metal powders 11 are used as main materials, and random amorphous flaky metal fine powders 10 having finer particle size than the metal powders 11 and produced by fracturing a metal fracture material by means of high-velocity gas swirling flow are used as sub-materials, and molding and sintering are performed in a state of dispersing the sub-materials (10) in the main materials (11). Thus, despite being a power metallurgical product, it is possible to obtain a metal product having a dense metallographic structure and excellent in properties such as mechanical strength.

    摘要： Processes for synthesizing metal nanoparticles, particularly copper nanoparticles, are described. The processes can involve reacting an insoluble complex of a metal salt with a reducing agent in a reaction mixture containing a primary amine first surfactant, a secondary amine second surfactant, and a diamine chelating agent third surfactant. More specifically, processes for forming copper nanoparticles can involve forming a first solution containing a copper salt, a primary amine first surfactant, a secondary amine second surfactant, and a diamine chelating agent third surfactant; allowing an insoluble complex of the copper salt to form from the first solution; combining a second solution containing a reducing agent with the insoluble complex; and forming copper nanoparticles from the insoluble complex. Such copper nanoparticles can be about 10 nm or smaller in size, more particularly about 3 nm to about 6 nm in size, and have a fusion temperature of about 200° C. or lower.

    摘要： This invention relates to organometallic precursor compounds represented by the formula (Cp(R′)x)yM(H)z-y, a process for producing the organometallic precursor compounds, and a method for depositing a metal and/or metal carbide layer, e.g., Ta metal and/or TaC layer, on a substrate by the thermal or plasma enhanced disassociation of the organometallic precursor compounds, e.g., by CVD or ALD techniques. The metal and/or metal carbide layer is useful as a liner or barrier layer for conducting metals and high dielectric constant materials in integrated circuit manufacturing.

    摘要： A method for producing granular metallic iron by heating and reducing a raw material mixture which includes an iron oxide-containing material, a carbonaceous reductant and a Li2O supplying material in a thermal reduction furnace, wherein the iron oxide-containing material includes a hematite-containing material, and the raw material mixture includes at least Fe, Ca, Mg, Si and Li as constituent elements in such a manner that slag which forms as a by-product during heating and reduction contains CaO, MgO, SiO2 and Li2O, has a Li2O content of 0.05% by mass or more, and the slag has a basicity [(CaO+MgO)/SiO2] in a range of from 1.5 to 1.9. This method enables granular metallic iron to be produced at a high productivity even when a hematite-containing material is used as the iron oxide-containing material.

    摘要： A metallic article is produced by furnishing one or more nonmetallic precursor compound comprising the metallic constituent element(s), and chemically reducing the nonmetallic precursor compound(s) to produce an initial metallic particle, preferably having a size of no greater than about 0.070 inch, without melting the initial metallic particle. The initial metallic particle is thereafter melted and solidified to produce the metallic article. By this approach, the incidence of chemical defects in the metal article is minimized. The melted-and-solidified metal may be used in the as-cast form, or it may be converted to billet and further worked to the final form.
