Abstract (en)
[origin: WO2008145928A2] The invention relates to a method for preparing mineral particles (p) from mineral particle precursors, said method comprising a step (E) that comprises injecting a fluid medium (F) containing said precursors in solution and/or dispersed in a solvent in a reactor containing CO2 at a supercritical state using an injection nozzle giving into an area where the supercritical CO2 is at a temperature higher than or equal to the conversion temperature of the precursors into corresponding mineral species, the invention also relates to particles (p) obtained according to the method and to the use thereof.
