  • Method of making iron powder - Mannesmann

    The "Journal Iron and Steel Inst.", London, 1956 pages 90 to 96, describes a method of making still lighter iron powder. Iron oxide (Fe 2 O 3) is reduced to sponge iron in a pure hydrogen atmosphere at temperatures from 760° to 980°C. The iron sponge is then broken into particles by means of wire brushes to obtain a powder having grain size ...
