Abstract

This invention aims at providing a method of obtaining fine alloy powders, which are extremely small in particle size, high in purity, and uniform in composition, providing fine alloy powders obtained by this method, and providing molding materials, slurries, and electromagnetic shielding materials, which use these fine alloy powders. This invention provides a fine alloy powder production method, which is characterized in that after performing the process of mixing at least a trivalent titanium compound and a complexing agent, which binds with the trivalent titanium ion, in an aqueous solution containing two or more types of metal ion, the two or more types of metal are made to deposit simultaneously. This invention also provides fine alloy powders, which are obtained by the above-described method, that are 1 to 100 nm in particle size, and preferably exhibit the characteristics of soft magnetic material, and molding materials, slurries, and electromagnetic shielding materials, produced by dispersing an abovementioned fine alloy powder in a resin.
