| titleOfInvention | Method for producing fine metal powder |
| abstract | The present invention is a novel metal fine powder which is more finer and more uniform in particle diameter than ever before, and which can produce a high-purity metal fine powder containing no impurities more cheaply, in a large quantity, and safely. An object of the present invention is to provide a manufacturing method, and by cathodic electrolytic treatment of an aqueous solution having a pH of 7 or less containing tetravalent titanium ions to reduce a portion of the tetravalent titanium ions to trivalent, thereby reducing the trivalent titanium ions to tetravalent. Reducing the aqueous solution of a reducing agent mixed with titanium ions, adding and mixing a water-soluble compound of at least one metal element, which is the basis of the fine metal powder, to the reducing agent aqueous solution to oxidize trivalent titanium ions to tetravalent. It is characterized in that fine metal powder is prepared by reducing and precipitating ions of metal elements by the action. |
