Copper powder for conductive paste, and conductive paste
A copper powder for a conductive paste contains 0.1 atm%-10 atm% of Si (silicon) and 0.1 atm%-10 atm% of In in the particle. It is preferable that the copper powder for a conductive paste contains 0.1 atm%-10 atm% of Ag (silver) in the particle. It is also preferable that the copper powder for a c...

Summary: | A copper powder for a conductive paste contains 0.1 atm%-10 atm% of Si (silicon) and 0.1 atm%-10 atm% of In in the particle. It is preferable that the copper powder for a conductive paste contains 0.1 atm%-10 atm% of Ag (silver) in the particle. It is also preferable that the copper powder for a conductive paste contains 0.01 atm%-0.5 atm% of P (phosphorus). The ratio of Si/In (atm ratio) is preferably 0.5-5. The copper powder for a conductive paste is preferably manufactured by an atomization method. |
