ELABORATION DE LA POUDRE DE FER PAR ELECTROREDUCTION DES OXYDES DE FER OU HYDROXYDES DE FER DANS UNE SUSPENSION ALCALINE

Abstract

The principal objective of this work consists to study the procedure of electrochemical elaboration of iron powder on metallic cathode. Many parameters susceptible to have an influence were studied: The nature of alkaline solution (NaOH, KOH), the iron oxide or hydroxide concentration, the current density, the electrolyze time, the agitation mode and the nature of the cathode. This subject permits also to define the conditions to obtain a co-deposition iron-metal and so easily doped iron. Under this aspect, successive tests were realized in order to characterize the obtained product. The X rays diffraction, optical microscopy, SEM and EDS were used.
