Abstract
(EN)
The present invention relates to mixed silver powder and a conductive paste comprising same, wherein, by mixing two or more types of spherical silver powder having different properties, the disadvantages of the respective types of powder can be minimized and the advantages thereof can be maximized, thereby improving the characteristics of products. In addition, according to the present invention, by comprehensively controlling the particle size distribution of surface-treated mixed silver powder and the particle diameter and specific gravity of primary particles, a high-density conductor pattern, a precise line pattern, and the suppression of aggregation over time can be simultaneously achieved.

La présente invention concerne une poudre d'argent mixte et une pâte conductrice la comprenant. Le mélange de deux types ou plus de poudre d'argent sphérique ayant des propriétés différentes permet de réduire au minimum les inconvénients des types respectifs de poudre et de maximiser leurs avantages, ce qui permet d'améliorer les caractéristiques des produits. De plus, selon la présente invention, le contrôle exhaustif de la distribution de la taille des particules de la poudre d'argent mixte traitée en surface et du diamètre des particules, ainsi que de la gravité spécifique de particules primaires, permet d'obtenir simultanément un tracé conducteur de haute densité, un tracé de ligne précis et de supprimer l'agrégation due au temps.
