METHOD FOR PRODUCING NICKEL POWDER

摘要

Provided is nickel powder obtained by adding a seed crystal to a nickel ammine complex solution and causing a hydrogen reduction reaction at high temperature and pressure, the nickel powder producing no dust when handled, and allowing efficient loading into a container. A method for producing nickel powder characterized in that 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 is hydrogen-reduced at high temperature and pressure in a pressure container, yielding a nickel powder from the mixed slurry.
