Production of Iron Nanopowders by the Electric Explosion of Wire

Abstract:

The work presents the study of the properties of nanopowders produced bythe electric explosion of wire (EEW) in the atmosphere of Ar, CO, CO₂, N₂. It was established that with the increase of theelectric strength of a gas the wire acquires more energy, enabling the reduction of a particle average size. The EEW in gaseous media that have high dissociation energy (N₂ and CO) produces metal powders that consist of crystalline α-Fe и γ-Fe. EEW products obtained in СО₂ consist of α-Fe and bivalent iron oxide.
