Abstract

La présente invention concerne un procédé de formation d'une particule support à base de calcium constituée de matériau à base de calcium, d'un agent actif, avec ou sans modification de surface et d'un agent stabilisant. L'invention concerne également la composition associée. La particule à base de calcium est représentée par la formule générale Cax(PO4)y(OH)zR et peut également comprendre un substituant de silice ou d'oxyde de silice. R désigne un agent actif ou des agents actifs tels qu'une molécule organique ou inorganique qui comprend des marqueurs, des amines, des thiols, des époxydes, des organosilicones, des organosilanes, des sulfates et des agents hydrosolubles et, si besoin, une modification de surface, S, qui peut être organique ou inorganique. Un agent stabilisant peut être nécessaire pour maintenir une dispersion des particules en milieu aqueux. Comme exemples de matériau modificateur de surface et d'agents stabilisants, on trouve des sels inorganiques d'aluminium et de bore ou des matières organiques telles que des organosilanes ou des polymères de faible poids moléculaire. Ainsi, la particule peut être utilisée dans diverses applications comprenant n'importe quel environnement sélectionné parmi divers environnements à haute température, à pH acide, neutre ou basique, ou de pression. Les particules supports présentent des applications aussi diverses que dans la fabrication du papier, le traitement de l'eau, le traçage chimique, les soins personnels, la lutte microbiologique, la récupération du pétrole, l'apport de polymères, par exemple.
