| Abstract: | Based on using chemical replacement for copper silver metal powder , adding masking agent to maximize the effect of eliminating copper ammonia complex metric ions adsorption on copper powder surface that will realize silver continuous coating on the copper powder surfaces. Analyses the principle of masking and the influencing of mole ratio, coating, and temperature to the conductivity of bimetallic powder. Experimental results show that after adding the ionic masking agent, effectively improve the copper powder antioxidant properties, and the main influence factors is the coated and mole ratio. |
