Abstract
Magadiite varieties isomorphically substituted with aluminum and their aluminosilicic acid derivatives retaining the framework topology of m agadiite are recrystallized, after incorporation by ion exchange of fo ur TPA and TEA ions, to MFI-and MEL-type zeolites, respectively. The r ecrystallization degree and the size and shape of the zeolite crystall ites formed can be controlled by the amount of template applied. Parti al recrystallization results in products which promise to be advantage ously applicable as catalysts because of the small crystallite size of the zeolitic component.
