Abstract

La présente invention a pour objet un procédé de préparation de particules minérales (p) à partir de précurseurs d'espèces minérales, ledit procédé comprenant une étape (E) dans laquelle on injecte un milieu fluide (F) comprenant lesdits précurseurs, en solution et/ou dispersés dans un solvant dans un réacteur contenant du CO2 à l'état supercritique, au moyen d'une buse d'injection débouchant dans une zone où le CO2 supercritique est à une température supérieure ou égale à la température de conversion des précurseurs en les espèces minérales correspondantes. L'invention concerne également les particules (p) telles qu'obtenues selon ce procédé, ainsi que leurs utilisations.
