Metal Oxides Synthesis,rting materials (AlOOH) for catalysts, and many other oxides. Oxides were also produced in batch reactors for long reaction time but with larger size. Organic capping ligands were successfully used to control and stabilize particles size (TiO., Fe.O., Cu, CeO.). Oxide nanoparticles could also be synthesized via other chemical reactions in SCW.

Introduction,d a liquid, and has a strong solubility that changes significantly near its CP. Small changes in pressure or temperature result in large variation in solubility, allowing production of fine particles via precipitation of a solute from supercritical solution by rapidly exceeding the saturation point

Supercritical Water Process,es dramatically due to low dielectric constant (ɛ) of SCW. Therefore, fine particles (e.g., metal oxides) are rapidly synthesized (e.g., 0.4 s∼2 min) in a continuous SCW process. In the oxide synthesis, an ionic metal salt is first hydrolyzed to metal hydroxide, which is then dehydrated to form meta

Other Materials Synthesis,ic phosphates were produced that have important industrial uses, e.g., as catalysts, ion-exchange materials, solid electrolytes for batteries and synthetic replacements for bones and teeth. Submicron particles of LiFePO. were produced in SCW from . solution in batch and flow reactors. Much smaller a
