    • A preparation method of a copper particle composition includes dissolving a copper carboxyl compound, or a carboxyl group-containing compound and a copper salt, in a solvent to prepare a copper(II) precursor solution; putting a weak reducing agent with a standard reduction potential of −0.2 to −0.05V to the prepared copper(II) precursor solution to assemble a plurality of Cu2O fine particles having an average diameter of 1 to 100 nm with a standard deviation of 0 to 10%, thereby forming spherical Cu2O assembly particles having an average diameter of 0.1 to 10 μm with a standard deviation of 0 to 40%; reducing the spherical Cu2O assembly particles into copper particles by using a reducing agent; and separating the copper particles from the result product. Thus, copper particles can be produced fast, economically, and the obtained copper particles have good crystallinity and good resistance against oxidation.
    • 铜颗粒组合物的制备方法包括将铜羧基化合物或含羧基化合物和铜盐溶解在溶剂中以制备前体铜(II)溶液; 将具有-0.2〜-0.05V的标准还原电位的弱还原剂加入到所制备的铜(II)前体溶液中,以将标准偏差为0的平均直径为1〜100nm的多个Cu 2 O微粒组装成 10%,由此形成平均直径为0.1至10μm的球形Cu2O组装颗粒,标准偏差为0至40%; 通过使用还原剂将球形Cu2O组装颗粒还原成铜颗粒; 并从结果产物中分离出铜颗粒。 因此,可以快速,经济地制造铜粒子,所得到的铜粒子具有良好的结晶性和良好的抗氧化性。
