Abstract

Combining the reduction of the mineral oxide to a liquid metal and its rapid solidification provides an energetically favorable route tod provide metastable metallic particles or powders. Such an option is available with the Sustained Shockwave Plasma (SSP) reactor in which the mineral oxide is reduced using a carbon-based reductant within the plasma medium and subsequently rapidly solidified. This paper examines the degree of metastability of these metal particles using optical, electron and Auger microscopy and discusses the potential of this processing route.
