Title (EN) SILVER POWDER, MANUFACTURING METHOD THEREFOR, AND CONDUCTIVE PASTE
(FR) POUDRE D'ARGENT, SON PROCÉDÉ DE FABRICATION ET PÂTE CONDUCTRICE
(JA) 銀粉およびその製造方法、ならびに導電性ペースト
Abstract:
(EN) Provided is a silver powder with which it is possible to form a conductive film having superior conductivity, and which does not clump together to form lumps over time and thus has good preservation stability. Also provided are a manufacturing method for silver powder, and a conductive paste using the silver powder. The silver powder has an alkenylsuccinic anhydride and/or an alkenylsuccinic acid on the surface.
(FR) L'invention concerne une poudre d'argent avec laquelle il est possible de former un film conducteur ayant une conductivité supérieure, ladite poudre ne s'agglutinant pas pour former des grumeaux au fil du temps et présentant donc une bonne stabilité de conservation. L'invention concerne également un procédé de fabrication de poudre d'argent et une pâte conductrice utilisant la poudre d'argent. La poudre d'argent possède un anhydride alcénylsuccinique et/ou un acide alcénylsuccinique sur la surface.
(JA) 優れた導電性を有する導電膜を形成することができ、経時により凝集し塊を生じることなく保存安定性が良好な銀粉および銀粉の製造方法、ならびに前記銀粉を用いた導電性ペーストを提供する。 前記銀粉は、アルケニルコハク酸無水物および/またはアルケニルコハク酸を表面に有するものである。
