    • 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.
    • 包含表面活性剂护套和有机化合物护套的超细复合金属颗粒包围金属芯,其中通过有机金属化合物还原沉淀获得的金属原子已凝聚,粒径为1〜100nm。 超细复合金属颗粒可以包括表面活性剂护套,其包围金属芯,其中通过由无机金属化合物的还原沉淀获得的金属原子已凝聚。 通过使用表面活性剂在非水溶剂中制造有机金属化合物或无机金属化合物的胶体溶液,通过在该非极性溶剂中形成超细颗粒前体,并且通过向其中添加还原剂来还原超细颗粒前体而获得超细复合金属颗粒 胶体溶液,从而形成直径为1至100nm的超细复合金属颗粒,并且在金属芯周围至少具有表面活性剂护套。
