Title (EN) SILVER PARTICLES CONTAINING COPPER, METHOD FOR PRODUCING THE SAME, AND DISPERSION USING THE SAME

Abstract:
(EN) Provided is a method suitable for the simple, mass production of nanoparticles having a uniform grain size, and silver particles produced by the same production method. One or more selected from the group consisting of copper, copper compounds, and copper ions is added prior to completion of the reduction reaction during the silver particle reaction in which a silver compound solution, protector, and reducing agent solution are mixed and reduction is performed.  As a result, regardless of the reaction scale, it is possible to produce particles having a uniform grain size by a reaction in which silver particles are obtained such that the average grain size in the solution is 1 to 100 nm.
(FR) L'invention concerne un procédé approprié pour la production de masse simple de nanoparticules ayant une taille de grain uniforme, et des particules d'argent produites par ce procédé de production. Un ou plusieurs éléments sélectionnés dans le groupe consistant en le cuivre, les composés de cuivre et les ions de cuivre sont ajoutés avant la fin de la réaction de réduction pendant la réaction des particules d'argent pendant laquelle une solution de composé d'argent, un protecteur et une solution d'agent de réduction sont mélangés et une réduction est effectuée. En conséquence, indépendamment de l'échelle de la réaction, il est possible de produire des particules ayant une taille de grain uniforme par une réaction pendant laquelle des particules d'argent sont obtenues de sorte que la taille de grain moyenne dans la solution soit de 1 à 100 nm.
(JA) 粒子径の揃ったナノ粒子の簡便且つ大量生産に適した製造方法及び該製造方法によって製造した銀粒子を提供することを目的とする。 銀化合物溶液、保護剤、及び還元剤溶液を混合して還元する銀粒子反応において、還元反応終了前に銅、銅化合物及び銅イオンからなる群より選ばれる1種以上を添加する。これによって、溶液中における平均粒子径が1~100nmであるような銀粒子を得る反応操作においても、反応スケールに関わらず粒子径の均整なものを得ることができる。
