ABSTRACT:
A process for production of a chain metal powder, which comprises the steps of reducing metal ions contained in an aqueous solution, while applying a magnetic filed to the solution, in the presence of both a reducing agent capable of generating a gas during the reduction of metal ions and a foamable water soluble compound, through the generation of a gas, a bubble layer on the surface of the aqueous solution to form a chain metal powder, separating the bubble layer formed on the surface of the aqueous solution from the solution, and collecting the chain metal powder contained in the bubble layer.
