Abstract
A process is provided for the production of a nickel metal powder by reduction of an ammoniacal nickel (II) carbonate solution essentially free of metallic nickel. A soluble silver salt is added in an amount to provide a soluble silver-to-nickel weight ration of 1.0 to 10.0 grams per kilogram of nickel, an organic dispersant, such as gelatin, is added in the amount of 5.0 to 20.0 grams per kilogram of nickel Ni (II), together with a spheroid-promoting agent such as anthraquinone in an amount of about 1.0 to 5.0 grams per kilogram of nickel. The solution is heated to a temperature in the range of 150 to 180 °C, with agitation, under a hydrogen pressure of about 3.5 MPa for a time sufficient to reduce the ammoniacal ammonium nickel (II) carbonate solution to micron-sized nickel metal powder. A high purity, micron-sized nickel metal powder of generally spheroid particulate configuration is produced. The nickel metal powder has an average particle size of about 0.5 microns. The metal powder is characterized in having an iron impurity content of less than 100 ppm.
