Title:
OXIDATION STABILITY-IMPROVED SILVER NANO POWDER PREPARED BY WET PROCESS AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2020/222542
Kind Code:
A1
Abstract:
The present invention relates to an oxidation stability-improved and highly pure silver nano powder prepared by a wet process and a method for preparing same, and more specifically, to a highly pure silver (Ag) nano powder and a method for preparing same, wherein: the wet process can reduce time and costs required for the preparation compared to a dry process and does not require a neutralization step for adjustment into an appropriate pH because a basic solution is not used; and the powder has an remarkably improved oxidation stability, and thus shows enhanced electrical properties, compared to the conventional nano powder, thereby finding easy applications in various fields such as an electrode and a paste.
