Study of Products of Electrical Explosion of Iron Wires in Argon-Oxygen Mixture

Abstract:

Results of the study of characteristics of iron nanopowders obtained by electrical explosion of wires in argon and argon-oxygen media are presented. It was found that adding oxygen at a rate of 0.02 g_O2/g_Fe allows to obtain iron powders resistant to fast air oxidation. The increasing rate of oxygen addition leads to the formation of γ-Fe₂O₃
