Synthesis Of Nanostructured Materials By Inert-Gas Condensation Methods

Abstract

This chapter discusses the synthesis of nanostructured materials by inert-gas condensation (IGC) methods. Nanostructured materials are single-phase or multiphase polycrystalline solids with a typical average grain size of a few nanometers, typically less than 100 nm. Such materials exhibit properties that are substantially different from and are often superior to those of conventional coarse-grained materials, due to their unique microstructure. Because the grain sizes are so small, a significant volume fraction of the atoms resides in grain boundaries. IGC is a simple method involving evaporation of material from a source in a flowing gas, followed by condensation into nanoparticles in the cooler parts of the system. Synthesis of nanostructured materials by IGC yields ultrafine-grained materials with narrow grain size distributions, clean grain boundaries, and excellent resistance to grain growth owing to the high degree of physical and chemical control over various parameters, which results in narrow particle/grain size distribution. The chapter focuses on the critical dependence of the size of the nanomaterial on the different process parameters. © 2007 William Andrew Inc. Published by Elsevier Inc. All rights reserved.
