Abstract:
A process for the manufacture of a colloidal suspension of Offretite, wherein a synthesis mixture having a molar composition, when calculated in terms of oxides, in the following ranges: K.sub.2 O:Al.sub.2 O.sub.3 0.25 to 0.5:1 (TMA).sub.2 O:Al.sub.2 O.sub.3 at least 2.0:1 SiO.sub.2 :Al.sub.2 O.sub.3 8 to 10:1 H.sub.2 O:Al.sub.2 O.sub.3 80 to 100:1  wherein TMA represents the tetramethylammonium cation, is subjected to thermal treatment at a temperature and for a time sufficient to form a colloidal suspension of Offretite having a maximum dimension of at most 100 nm.
