Abstract A new layered microporous (alumino) silicate showing (100) ferrierite layers and called PREFER was synthesised from fluoride-containing aqueous media in the presence of a novel bulky template, the 4-amino-2,2,6,6-tetramethyl-piperidine. Calcination at about 500°C of this ‘as-made’ product leads to FER-type zeolite by a transformation occurring through the intermediate formation of poorly organised phases. The whole set of results obtained by several techniques such as variable-temperature XRD, chemical and thermal analyses and 29Si MAS NMR spectroscopy are consistent with a 2D→3D transformation process. Indeed, during the calcination, the (100) ferrieri...
