| description | The present invention relates to a process for preparing mineral particles (p) from mineral species precursors, said process comprising a step (E) in which a fluid medium (F) containing said precursors in solution and/or dispersed in a solvent is injected into a reactor containing CO2 in the supercritical state by way of an injection nozzle opening into a zone where the supercritical CO2 is at a temperature greater than or equal to the temperature for conversion of the precursors into corresponding mineral species. The invention also relates to the particles (p) as obtained by the process, as well as uses thereof. |
