Description

BACKGROUND OF INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a copper fiber body to be incorporated in various resin compositions, rubber compositions, low melting metals, coating compounds or adhesives as an electrically-conducting material, electromagnetic barrier material, reinforcing material or the like.

[0003] 2. Related Art

[0004] As a copper fiber body there has been widely known copper whisker. In 1956, S. S. Blenner obtained copper whisker by reducing a copper halide in hydrogen gas. In 1965, Tachibana and Kishi succeeded in producing a considerably small copper whisker while controlling the rate of reduction reaction of copper halide with carbon dioxide gas produced by the reaction of charcoal with air in a closed air system.

[0005] However, these methods are disadvantageous in that the resulting yield is too low. Further, the resulting copper whisker cannot be considered small enough in size. Thus, such a copper whisker can be hardly incorp...
