Magadiite varieties isomorphically substituted with aluminum and their aluminosilicic acid derivatives retaining the framework topology of magadiite are recrystallized, after incorporation by ion exchange of four TPA and TBA ions, to MFI- and MEL-type zeolites, respectively. The recrystallization degree and the size and shape of the zeolite crystallites formed can be controlled by the amount of template applied. Partial recrystallization results in products which promise to be advantageously applicable as catalysts because of the small crystallite size of the zeolitic component.
