Title:
COPPER POWDER FOR CONDUCTIVE PASTE, AND CONDUCTIVE PASTE
Document Type and Number:
WIPO Patent Application WO/2011/145378
Kind Code:
A1
Abstract:
Provided is a novel copper powder for a conductive paste wherein it is possible to fully control the sintering temperature property between the temperature range of 500 to 900°C while maintaining oxidation resistance. Specifically, provided is a copper powder for a conductive paste, which contains Si (silicon) and P (phosphorus), wherein the Si concentration is 0.01 atm% or more and less than 1.2 atm%, and the Si equivalent (Si concentration × D50) calculated by multiplying the Si concentration with D50 (µm) is 3.50 or less.
