COPPER POWDER FOR ELECTROCONDUCTIVE PASTE, AND ELECTROCONDUCTIVE PASTE

摘要

PROBLEM TO BE SOLVED: To provide a copper powder which does not impair both of oxidation resistance and a balance of electroconductivity though the particle size is very small; a copper powder for an electroconductive paste, of which the shape and the particle size is also small and which contains little oxygen; and the electroconductive paste. SOLUTION: The copper powder for the electroconductive paste contains 0.1 to 10 atm% Si (silicon) inside the particle. The copper powder contains 0.01 to 0.3 atm% P (phosphorus) inside the particle.
