Herstellung feines Nickelverbundpulver

摘要

Composite nickel fine powder herein disclosed is characterized in that at least one member selected from the group consisting of oxides and complex oxides which comprise at least one metal element having an atomic number ranging from 12 to 56 or 82 and belonging to Group 2 to 14 of Periodic Table is carried on the surface of metal nickel fine particles. The composite nickel fine powder can be prepared by, for instance, adding an aqueous solution containing at least one member selected from the group consisting of water-soluble salts of the foregoing metal elements to a slurry containing metal nickel fine particles or surface-oxidized metal nickel fine particles; and then adjusting the pH of the mixture with an acid or an alkali to thus carry the metal oxide and/or complex oxide derived from the water-soluble salt on the surface of the metal nickel fine particles.
