NICKEL POWDER PRODUCTION PROCESS

摘要

PROBLEM TO BE SOLVED: To provide a nickel powder obtained by adding a seed crystal to a nickel ammine complex solution and carrying out a hydrogen reduction reaction at high temperature and high pressure, that does not generate dust during handling and that allows a container to be efficiently filled therewith.SOLUTION: Provided is a nickel powder production process characterized in producing a powder of nickel from a mixed slurry formed by adding a seed crystal and a surfactant having a nonionic or anionic functional group to a solution containing a nickel ammine complex in such a manner that the mixed slurry is hydrogen-reduced under a high temperature and high pressure condition within a pressure vessel.SELECTED DRAWING: Figure 1
