From the author: The effects of oxidation and particle shape on critical volume fractions of silver-coated copper powders in conductive adhesives are investigated. Silver-coated copper powders with spherical and flake-shaped particles were oxidized at temperatures of 30[degrees]C, 175[degrees]C and 240[degrees]C for two hours and dispersed in an epoxy matrix. As silver-coated copper powders are oxidized at 30[degrees]C and 175[degrees]C, the critical volume fractions of the conductive adhesives are slightly affected by oxidation and particle shape at these temperatures. As the oxidation temperature approaches 240[degrees]C, the critical volume fractions of the conductive adhesives are strongly affected by oxidation temperature and particle shape, owing to the formation of oxides such as [Cu.sub.2]O on the surface of silver-coated copper powder--Cu diffuses from the interior to the surface of silver-coated copper powder and reacts with the oxygen in the air. Silver-coated copper powder with flake-shaped particles shows lower critical volume fractions in conductive adhesives than silver-coated copper powder with spherically shaped particles. Polym. Eng. Sci. 44:2075-2082. 2004. [c] 2004 Society of Plastics Engineers.
