PROCESS FOR PREPARING A COMPOSITION COMPRISING SYNTHETIC MINERAL PARTICLES AND COMPOSITION

摘要

A process for preparing a composition including synthetic mineral particles, in which a hydrogel which is a precursor of the synthetic mineral particles is prepared via a coprecipitation reaction between at least one compound including silicon, and at least one compound including at least one metal element, characterized in that the coprecipitation reaction takes place in the presence of at least one carboxylate salt of formula R2—COOM′ in which: —M′ denotes a metal chosen from the group made up of Na and K, and —R2 is chosen from H and alkyl groups including fewer than 5 carbon atoms. A composition including synthetic mineral particles which is obtained by such a process is also described.

1. A process for preparing a composition comprising synthetic mineral particles, in which a hydrogel precursor of said synthetic mineral particles is prepared by a coprecipitation reaction between:
at least one compound comprising silicon, and at least one compound comprising at least one metal element,wherein said coprecipitation reaction takes place in the presence of at least one carboxylate salt of the formula R2—COOM′ in which:
M′ denotes a metal chosen from the group formed of Na and K, and R2 is chosen from H and alkyl groups having fewer than 5 carbon atoms.
