    摘要: Dispersed, crystalline, stable to oxidation copper particles are prepared in the absence of polymeric dispersants by rapidly reducing a Cu(I) salt with an Fe(II) carboxylic acid complex in water. The resulting microns sized copper powders contain only organics which decompose at temperatures low enough not to interfere with sintering processes and the formation of conductive copper structures.
