Abstract
A method for preparing a composition including synthetic mineral particles, in which: a hydrogel that is a precursor of the synthetic mineral particles is prepared, and the hydrogel is subjected to a hydrothermal treatment, characterized in that at least one step of the hydrothermal treatment is carried out with the addition of at least one carboxylate salt to the treatment medium, the carboxylate salt having the formula R—COOM′, where M′ denotes a metal selected from the group consisting of Na and K, and R is selected from H and the alkyl groups that include fewer than 10 carbon atoms.
