| titleOfInvention | Manufacturing method of fine spherical metal nickel fine powder |
| abstract | According to the invention, the formula Ni (CO 3 ) x (OH) y ( In this formula, x and y are numbers satisfying 0≤x≤1.5 and 0≤y≤3, respectively, and the nickel carbonate and / or nickel hydroxide are ammonia aqueous solution or ammonia, ammonium carbonate, ammonium bicarbonate Dissolved in an aqueous solution of a carbonate or hydrogen carbonate to make an aqueous solution of the obtained nickel salt into a W / O emulsion containing a droplet of the aqueous solution in a non-aqueous medium, and then a vaporizing component containing ammonia in the droplet was removed. Precipitating nickel carbonate in the droplets, thereby obtaining fine spherical nickel carbonate particles, and 0.01 to 30% by weight of alkaline earth elements, aluminum, silicon and rare earth elements as oxides. The nickel carbonate particles are heated by heating in a hydrogen atmosphere in the presence of a fusion inhibitor consisting of at least one selected elemental compound. A method for producing a fine spherical metal nickel fine powder having an average particle diameter of 0.05 to 10 µm is provided, including a second step of reducing the metal nickel particles. |
