| abstract |
The present invention is a method for preparing mineral particles (p) from a mineral species precursor, wherein the fluid medium (F) containing the precursor dissolved and / or dispersed in a solvent is treated with CO 2 . the reactor containing a supercritical state, step comprises injecting an injection nozzle supercritical CO 2 is open in a region which is at a temperature above the conversion temperature of the corresponding mineral species precursor (E ). The invention also relates to the particles (p) obtained by the method and their use. |
