Crystallization of TS-1 and TS-2 Zeolites with Contribution of Solid- Solid Transformations.

The synthesis of TS-1 and TS-2 zeolites from SiO2–TiO2 xerogels wetness impregnated with solutions of the structure-directing agent proceeds mainly through solid–solid transformations which allow the raw amorphous network to be reordered into crystalline frameworks.
