Abstract: This paper reviews methods of producing particles using supercritical fluids. First it explains the properties of supercritical fluids, phase behaviors of supercritical solutions, and reaction equilibrium and reaction rate in supercritical fluids. Next it explains the principles of new crystallization methods using supercritical fluids. These explanations cover the RESS method, GAS method, retrogressive crystallization, supercritical drying, and hydrothermal synthesis in SCW The use of rapid expansion of super… Show more

“…There exist two main routes of material elaboration in supercritical media: processes using a physical transformation (rapid expansion of supercritical solution, gas antisolvent, …) [1][2][3][4] and less commonly processes using a chemical transformation. [5][6][7][8] This work refers to the chemical transformation of metal precursors in a supercritical fluid. More precisely the metal precursor is thermally decomposed to metal atoms which give access to the nucleation and growth of particles.…”
