Abstract

L'invention a pour objet un procédé de préparation d'un aluminosilicate cristallin suivant lequel a) on prépare un mélange réactionnel comprenant du sodium, de la silice, de l'alumine et de l'eau en un rapport déterminé par le produit qu'on souhaite obtenir comme aluminosilicate cristallin, b) on soumet le mélange réactionnel à un malaxage par cisaillement haute intensité, c) on maintient le mélange réactionnel résultant à une température d'environ 25 à 125 degrés C jusqu'à ce qu'il y ait formation de cristaux, et d) on sépare les cristaux de la liqueur-mère.
