Abstract

A process for the production of a metal or metal alloy powder with flake-shaped particles comprises mechanically crushing a ductile starting material. A foreign substance which forms a separate phase between the crystallites of the starting material is added thereto to facilitate crushing the starting material, while retaining the original workability thereof.
