Preparation of titanium nanopowders covered with organics by pulsed wire discharge

Abstract

Titanium nanopowders covered with organics which have never been obtained by any previous methods are prepared by pulsed wire discharge (PWD) using titanium wires in helium gas with oleic acid vapor/mist. The prepared titanium particles covered with titanium oleate had not oxidized 1 month after preparation at room temperature in air. From these results, we conclude that the preparation of titanium nanopowder with an oxidation-resistant coating of titanium oleate can be successfully achieved by PWD in oleic acid/vapor mist. © 2010 Acta Materialia Inc.
