摘要：

A hydrothermal synthesis process working in supercritical conditions (T>374 degrees C, P>22 MPa) and in a continuous mode has been developed for inorganic nanopowder synthesis. This paper presents a review of the past 5 years of research conducted on this process. Numerous materials (oxides: ZrO(2), TiO(2), Fe(2)O(3)..., ferrites: Fe(2)CoO(4)..., or BaZrO(3)) were obtained with specific features. Some technical issues have been solved, that are presented here. Heat transfer was studied, leading to a more efficient design of the reactor. Future developments have been examined through process engineering, in which our group is engaged, especially through CFD modelling. (C) 2008 Elsevier B.V. All rights reserved.
