摘要：A melt of nickel nitrate hydrate is introduced as droplets or liquid flow into aheated reaction vessel and thermally decomposed in a gas phase at a temperature of1200° C. or more and at an oxygen partial pressure equal to or below the equilibrium
oxygen pressure of nickel-nickel oxide at that temperature to manufacture a highlycrystalline fine nickel powder with an extremely narrow particle size distribution. Theoxygen partial pressure during the thermal decomposition is preferably 10Pa or less, anda metal other than nickel, a semimetal and/or a compound of these may be added to thenickel nitrate hydrate melt to manufacture a highly crystalline nickel alloy powder orhighly crystalline nickel composite powder. The resultant powder is suited in particular tothick film pastes such as conductor pastes for manufacturing ceramic multilayerelectronic components.
