Abstract

Abstract

The experimental setup used to synthesize metal oxide nanopowders by electrical explosion of wires (EEW) was designed. Al2O3 nanopowders were synthesized successfully. The average size of the nanoparticle was 64.9 nm. Physical conditions for producing Al2O3 nanopowders by EEW were investigated. Research results show that the conditions affect the size of powders greatly. The lower the pressure in the chamber is, the smaller the particle size is. The particle size is proportional to the diameter of the wire. The smaller the diameter of the wire is, the smaller the particle size is. The particle size has some relation with the storage energy of the capacitor, too.
