Conductive Paste Silver Coated Copper Powder Ag Coated Cu

Properties for Ag Coated Cu Powder:

1 .The silver coated copper powder shape, bulk density , tap density is mainly determined by the material properties of copper , silver coated has little effect on these properties.

2 .The silver coating on the copper particle has some influence , the particle size D50 of the copper powder is increasing with the silver content distribution decreases , when the silver content is greater than 20%, D50 starts becomes large.

3. silver coating of copper powder compaction wallet greater impact resistance , compaction resistance are coated with increasing silver content decreases ; when coated silver content greater than 20% , the resistance gradually decreased to reduce compaction and stabilized.

4.The impact of the specific surface area of silver coated copper : low amount of silver coated copper powder , the specific surface area increases with increasing silver content ; coated Ag content greater than 5% , the specific surface area with the package overlying silver content increases.

5 .silver coated copper placed in the air , compaction resistance are larger. From the comparison of silver -coated, low silver content than the high variation in silver content.

6. the amount of silver coated copper powder different oxidation temperature began to differ. Low silver content of the oxidation temperature lower than the high silver content
