This book details progress in use of supercritical water (SCW) to synthesize nano- and micro- oxides, inorganic salts and metal particles, and shows how polymer/biomass particles can be produced by the precipitation of solutes from SCW.

Supercritical Water Process.- Metal Oxides Synthesis.- Nano-Structured Coatings.- Other Materials Synthesis.- Fine Organics Particles by Precipitation of Solute.- Conclusions and Future Prospects.
This book shows how to use supercritical water (SCW) to synthesize nano- and
micro- oxides, inorganic salts and metal particles and its recent
advancement. Also polymer/biomass particles can be produced by using the
method of precipitation of solutes from SCW. The particles can be used as
catalysts for biomass conversions, materials in ceramics & electronic devices
and composite materials. Particles are easily produced continuously in
a flow reactor in short reaction times or synthesized in a batch reactor in long reaction times. Besides the synthesis process, the book also present studies of the properties of these materials. The size, size distribution, crystal growth & structure, and morphology of particles produced by supercritical water can be controlled by the feed concentrations, pH, pressures, temperatures, heating & cooling rates, organic modifications, reducing or oxidizing atmospheres, flow rates and reaction times.
