Abstract
L'invention vise un procédé de modification de matières cristallines siliciques, comprenant les étapes consistant à : i) mettre en contact la matière cristalline silicique avec une solution aqueuse de silicate de métal alcalin comprenant en outre un additif complexant les ions; et ii) évaporer l'eau. Elle vise également le composite susceptible d'être obtenu par ce procédé ainsi que l'utilisation d'une solution de silicate de métal alcalin pour l'inertage de matériaux cristallins siliciques, notamment l'amiante.
