Title:

METAL ALLOY FINE PARTICLES AND METHOD FOR PRODUCTION THEREOF

Document Type and Number:

WIPO Patent Application WO/2002/062509

Kind Code:

A1

Abstract:

A novel method for preparing fine particles comprising a transition metal and a noble metal which are monodisperse and have almost no particle diameter distribution, and are transferable to a CuAu-I type L1¿0? ordered phase, with safety and at a low cost, wherein a salt or a complex of at least one transition metal selected from Fe and Co and a salt or a complex of at least one transition metal selected from Pt and Pd (exclusive of the combination of Co - Pd) is dissolved in an organic solvent miscible with water or an alcohol in the presence of an organic protecting agent, and the resultant solution is heated under reflux in the presence of an alcohol in an inert atmosphere, to thereby prepare a binary alloy comprising a transition metal and a noble metal, or, a salt or a complex of at least one element selected from the group consisting of Cu, Bi, Sb, Sn, Pb and Ag is further dissolved in the above solvent and the resultant solution is heated under reflux in the presence of an alcohol in an inert atmosphere, to thereby prepare a ternary alloy comprising a transition metal, a noble metal and an additional element.
