Iron oxide (Fe2O3) nanoparticles were generated in a single step by wire explosion process (WEP). The influence of energy deposited to the exploding conductor and the ambient pressure on phase, size and shape of the particle were analysed. Oxygen is used as medium during wire explosion process to obtain iron oxide. The characteristics of the particles were analysed through WAXD and TEM. The thermodynamic aspects of nanoparticle formation by wire explosion process are detailed.

Abstract

The influence of energy deposited to the exploding conductor and the ambient pressure on phase, size and shape of the particle were analysed. Oxygen is used as medium during wire explosion process to obtain iron oxide. The characteristics of the particles were analysed through WAXD and TEM. The thermodynamic aspects of nanoparticle formation by wire explosion process are detailed.
