The chemical reduction method of silver coated copper powder refers to the process of using a reducing agent to reduce the ions in the main salt to elemental form and depositing on the surface of the substrate with autocatalytic ability in a metastable solution system. When the reducing agent is oxidized on the catalytically active surface, free electrons are generated. These free electrons can re...

The displacement reaction method is a common process for processing silver-coated copper powder. Because the surface activity of copper powder is very large, it is easy to oxidize, so it must be pretreated before coating the copper powder. 1. Put the required amount of copper powder into the pretreatment tank, and then wash with 15% 30% dilute sulfuric acid to keep the pH of the solution at 3 2. W...
