Polarization characteristics of the electrodeposition processes of Fe powders from sulfate and chloride electrolytes and the morphology of the ob- tained powders were investigated. The morphology depended on the anion pre- sence in the electrolyte but not on the current density in the investigated range. A characteristic feature of the dendritic powder with cauliflower endings ob- tained from sulfate electrolyte is the presence of cone-like cavities and the crys- tallite morphology of the powders surface. On the other hand, Fe powders elec- trodeposited from chloride electrolyte appear in the form of agglomerates. A soap solution treatment applied as a method of washing and drying provides good protection from oxidation of the powders.
