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

摘要

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 oxygon at a rate of 0.02 gO2/gFe allows to obtain iron powders resistant to fast air oxidation. The increasing rate of oxygen addition leads to the formation of γ-Fe_2O_3.
