Abstract:
The present invention relates to ear-of-rice-shaped copper particles. The technical gist thereof is a method of manufacturing ear-of-rice-shaped copper particles, ear-of-rice-shaped copper particles manufactured thereby, and a conductive paste using the same. The method includes a first step of preparing a copper precursor solution, a second step of adjusting the pH of the copper precursor solution, a third step of adding a zinc powder to the pH-adjusted copper precursor solution, a fourth step of synthesizing the ear-of-rice-shaped copper particles by stirring the copper precursor solution, to which the zinc powder is added, for a predetermined time, and a fifth step of separating, washing, and then drying the synthesized ear-of-rice-shaped copper particles.
