Since the particle size is small, the bulk density is low due to the presence of dust and irregularities when the powder is shipped as a nickel metal product, and there is a problem that an extra volume is required when filling the container.
  • nickel powder obtained by adding a seed crystal to a nickel ammine complex solution using an autoclave and carrying out a hydrogen reduction reaction at high temperature and high pressure has dust and unevenness when shipped as a nickel metal product as powder. Therefore, it solves the above-mentioned problem that the bulk density is low and an extra volume is required when filling the container.

In the nickel powder obtained in this way, nickel powder that does not generate dust during handling and can be efficiently filled into a container is provided.

  • the unevenness of the powder surface is suppressed and the surface has a smooth surface, and a nickel powder having a dense surface shape as shown in FIG. 2 can be obtained. Moreover, since a thing with a large particle size can be obtained, handling becomes easy and the industrial value is large.
