Patent 7510592 was granted and assigned to Sumitomo Electric Industries on March, 2009 by the United States Patent and Trademark Office.
A method of producing metal powder by reducing ions of a metal for precipitation by performance of a reducing agent in a liquid-phase reaction system, wherein the metal is precipitated as metal powder particles by being reduced under conditions in which the exchange-current density of an oxidation-reduction reaction between the metal ions and the reducing agent is 100 μA/cm2 or less, the exchange-current density being determined by the mixed potential theory.
