COMPOSITE COPPER PARTICLES AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
PROBLEM TO BE SOLVED: To provide composite copper particles exhibiting improved electrode continuity while maintaining a sintering commencement temperature comparable to sintering temperatures of conventionally used copper powders.SOLUTION: The composite copper particles of the present invention are provided by compositing, with a flat copper particle, a plurality of inorganic oxide particles finer than the flat copper particle. The inorganic oxide particles are localized on surfaces of the flat copper particle. The volume cumulative diameter Dspecific to cumulative volume=50 vol.% according to a laser diffraction scatter-style particle size distribution measurement method is preferably 0.1 μm or above and 10 μm or below. The aspect ratio expressed by d/t, namely the flat particle surface major axis diameter d-to-thickness t ratio, is preferably 5 or above and 30 or below. |
