Title (EN) METHOD FOR PREPARING SILVER POWDER
(FR) PROCÉDÉ DE PRÉPARATION DE POUDRE D'ARGENT
(KO) 은 분말의 제조방법
Abstract:
(EN) The present invention relates to a method for preparing agglomerated silver powder comprising: a reaction liquid preparation step (S11) for preparing a silver source solution containing silver (Ag) and preparing a reducing solution containing a reducing agent; and a silver reduction step (S12) for adding the reducing solution to the prepared silver source solution with a feed rate so as to precipitate agglomerated silver powder. The present invention can provide a method for preparing agglomerated silver powder, which can easily control the properties of agglomerated silver powder to be prepared such as a primary particle size and a specific surface area by adjusting the feed rate of a reducing solution, and a method for preparing flake silver powder by using the same.
(FR) La présente invention concerne un procédé de préparation de poudre d'argent agglomérée comprenant : une étape de préparation de liquide de réaction (S11) consistant à préparer une solution de source d'argent contenant de l'argent (Ag) et à préparer une solution de réduction contenant un agent réducteur ; et une étape de réduction d'argent (S12) consistant à ajouter la solution de réduction à la solution de source d'argent préparée avec une vitesse d'alimentation permettant de précipiter la poudre d'argent agglomérée. La présente invention peut fournir un procédé de préparation de poudre d'argent agglomérée qui peut facilement commander les propriétés de la poudre d'argent agglomérée à préparer, telles qu'une taille de particule primaire et une surface spécifique, par ajustement de la vitesse d'alimentation d'une solution de réduction, et un procédé de préparation de poudre d'argent en flocons l'utilisant.
(KO) 본 발명은 은(Ag)을 포함하는 은 소스 용액을 제조하고, 환원제를 포함하는 환원 용액을 제조하는 반응액 제조단계(S11) 및 상기 제조된 은 소스 용액에 투입속도를 갖고 상기 환원 용액을 투입하여 응집형 은 분말을 석출하는 은 환원단계(S12);를 포함하는 응집형 은 분말 제조방법에 관한 것으로, 환원 용액의 투입속도를 조절함으로써 제조되는 응집형 은 분말의 일차입자경 및 비표면적 등 특성 제어가 용이한 응집형 은 분말의 제조방법 및 이를 이용한 플레이크 은 분말의 제조방법을 제공할 수 있다.
