摘要： Provided are copper microparticles which have exceptional oxidation resistance, in which oxidation is reduced even when the copper microparticles are held at a firing temperature in an oxygen-containing atmosphere, and in which sintering also occurs. The copper microparticles have a particle diameter of 10-100 nm, have a surface coating material, and are such that, after the copper microparticles are held for one hour at a temperature of 400° C. in an oxygen-containing atmosphere, the particle diameter exceeds 100 nm while a copper state is retained.

摘要： A dielectric barrier discharge (DBD) plasma apparatus for synthesizing metal particles is provided. The DBD plasma apparatus includes an electrolyte vessel for receiving an electrolyte solution comprising metal ions; an electrode spaced-apart from the electrolyte vessel; a dielectric barrier interposed between the electrolyte vessel and the electrode such that, when the electrolyte solution is present in the electrolyte vessel, the dielectric barrier and an upper surface of the electrolyte solution are spaced-apart from each other and define a discharge area therebetween; and gas inlet and outlet ports in fluid communication with the discharge area such that supplying gas in the discharge area while applying an electrical potential difference between the electrode and the electrolyte solution cause a plasma to be produced onto the electrolyte solution, the plasma interacting with the metal ions and synthesizing metal particles. A method for synthesizing metal particles using a DBD plasma apparatus is also provided.

摘要： Novel metallic systems and methods for their fabrication provide an extreme creep-resistant nano-crystalline metallic material. The material comprises a matrix formed of a solvent metal with crystalline grains having diameters of no more than about 500 nm, and a plurality of dispersed metallic particles formed on the basis of a solute metal in the solvent metal matrix and having diameters of no more than about 200 nm. The particle density along the grain boundary of the matrix is as high as about 2 nm2 of grain boundary area per particle so as to substantially block grain boundary motion and rotation and limit creep at temperatures above 35% of the melting point of the material.

摘要： This invention aims at providing a carbon-coated metal powder having few impurities, a narrower particle size distribution, and sintering properties particularly suitable as a conductive powder of a conductive paste for forming internal conductors in a ceramic multilayer electronic component obtained by co-firing multilayered ceramic sheets and internal conductor layers; a conductive paste containing the carbon-coated metal powder; a multilayer electronic component using the conductive paste; and a method for manufacturing the carbon-coated metal powder. The carbon-coated metal powder has specific properties in TMA or ESCA measurements. The carbon-coated metal powder can be obtained by melting and vaporizing a metallic raw material in a reaction vessel, conveying the generated metal vapor into a cooling tube and rapidly cooling the metal vapor by endothermically decomposing a carbon source supplied into the cooling tube, and forming a carbon coating film on metal nuclei surfaces in parallel with generation of the metal nuclei.
