【 摘 要 】

This paper studies the reactivity of kaolinite and metakaolin in a fluorinated medium under hydrothermal conditions. This path of conventional zeolite synthesis did not yield promising results, although traces of different zeotypes did crystallize, such as the crystal structures Linde type Y (LTY), zeolite Na-P1 (GIS), chabazite-ca(CHA), sodalite (SOD), cancrinite (CAN) and Linde type A (LTA). Other zeolites reported in this study were zeolite ZSM-5 (MFI type structure)and zeolite ITQ (ISV type structure).The non-reacting starting material and the synthe sized products where characterized by x-ray diffraction, scanning electron microscopy, infrared spectroscopy by Fourier transformand thermogravimetric analysis. Theproducts of the synthesis are of interest because they can be used in different industrial applications.
