Abstract

A wide range of ultra-fine, nano-crystalline powders and suspensions have been produced using the Rapid Thermal Decomposition of precursors in Solution (RTDS) technology. These materials include single and multi-component iron-, zirconium-, titanium-, nickel-, and chromium-oxide/oxyhydroxide powders. RTDS, which was developed at Pacific Northwest Laboratory, is a flow-through hydrothermal process capable of producing nano-crystalline particulate material at rates of up to 100 grams of solid per hour. We present the results of characterization efforts on RTDS iron oxyhydroxide and zirconium oxide systems. As-collected RTDS suspensions were characterized using optical light scattering. Separated RTDS powders were evaluated using X-ray diffraction, electron microscopy, gas adsorption analysis, thermal gravimetric analysis, and chemical analysis.
