摘要： PROBLEM TO BE SOLVED: To provide new ultrafine composite metal particles having excellent dispersion stability and capable of controlling grain size, and simultaneously, to develop a manufacturing method capable of inexpensively mass-producing the ultrafine composite metal particles. SOLUTION: The ultrafine composite metal particles are characterized in that a surfactant sheath and an organic compound sheath derived from an organic metal compound surround a metal core in which metal atoms obtained by reduction precipitation from an organic metal compound have agglomerated. The ultrafine composite metal particle may comprise a surfactant sheath that surrounds a metal core in which metal atoms obtained by reduction precipitation from an inorganic metal compound have agglomerated. One manufacturing method comprises: a first stage of forming an ultrafine particle precursor by producing a colloidal solution of an organic metal compound or an inorganic metal compound in a nonaqueous solvent using a surfactant; and a second stage of reducing the ultrafine particle precursor by adding a reducing agent to this colloidal solution, thus forming ultrafine composite metal particles and having at least a surfactant sheath around a metal core.

摘要： PROBLEM TO BE SOLVED: To provide an ultrafine particle crystal composed of composite metal ultrafine particles having single crystal metal nuclei and to provide a crystal film of ultrafine particles, a crystal of ultrafine particles, and manufacturing methods therefor.
SOLUTION: Composite metal ultrafine particles each having a single crystal metal nucleus are used as basic particles and stacked three-dimensionally to obtain an ultrafine particle crystal film and ultrafine particle crystal. The ultrafine particle crystal has at least 10
2 μm
2 of 2-dimensional area and can be observed with an optical microscope. The ultrafine particle crystal film is formed on a substrate by immersing it in an heated organic solvent in which the metal composite ultrafine particles having a single crystal metal nuclei are dispersed. The ultrafine particle crystal is grown in a supersaturated condition by putting predetermined amount of the organic solvent and evaporating it gradually.

摘要： Ultrafine composite metal particles comprising a surfactant sheath and an organic compound sheath that surround a metal core in which metal atoms obtained by reduction precipitation from an organic metal compound have agglomerated, the particle diameter being 1 to 100 nm. The ultrafine composite metal particle may comprise a surfactant sheath that surrounds a metal core in which metal atoms obtained by reduction precipitation from an inorganic metal compound have agglomerated. The ultrafine composite metal particles are obtained by forming an ultrafine particle precursor by producing a colloidal solution of an organic metal compound or an inorganic metal compound in a nonaqueous solvent using a surfactant, and by reducing the ultrafine particle precursor by adding a reducing agent to this colloidal solution, thus forming ultrafine composite metal particles with a diameter of 1 to 100 nm and having at least a surfactant sheath around a metal cored.
