【 摘 要 】

The possibility of producing metallic tantalum nanopowders using electric explosion of Ta-wire was explored. The regimes of the electric explosion were determined which provided maximum level of energy brought into the wire. The basic properties of the obtained powders were examined using low-temperature nitrogen adsorption, atomic-emission spectrometry, as well as by means of transmission and scanning electron microscopes.
