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...
