SILVER-BISMUTH POWDER, CONDUCTIVE PASTE AND CONDUCTIVE FILM

摘要

PROBLEM TO BE SOLVED: To provide a silver-bismuth powder which has good solder wettability and a low volume resistivity and exerts excellent conductivity even in applications involving baking in a relatively high-temperature oxidative atmosphere (500°C or higher), a conductive paste and a conductive film.SOLUTION: A silver-bismuth powder comprises silver and bismuth in a mass ratio of silver to bismuth, silver:bismuth, of 95:5 to 40:60 and has an accumulation 50% particle size (D50) in the distribution of volume-based particle sizes of 0.1-10 μm, measured by the laser diffraction type particle size distribution measurement method, and an oxygen content of 5.5 mass% or lower.
