Abstract： |
The invention discloses a chemical silver plating preparing conducting resin method on the graphite powder surface in the chemical silver plating and micro-electronics connection material technique domain, which comprises the following steps: oxidizing the graphite powder in the air at 600-650DEG C; putting the dispersant, reducer and stabilizing agent in de-ionized water for reduced liquid; adding in graphite powder to stir; putting the silver nitrate in the de-ionized water; adding in ammonia and sodium hydroxide to get argentamine; putting the reduced liquid in the argentamine liquid to finish chemical silver plating on the graphite powder surface; filtering; separating and washing; drying in vacuum to get silver coated graphite powder. |
