RIOS-REYES, Carlos Alberto; DENVER-WILLIAMS, Craig  e  CASTELLANOS, Óscar Mauricio. Reactivity Study of Kaolinite and Metakaolinite in Fluoride Media under Hydrothermal Conditions. Ing. Univ. [online]. 2013, vol.17, n.1, pp.183-203. ISSN 0123-2126.

This paper studies the reactivity of kaolinite and metakaolin in a fluori-nated 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 synthesized products where characterized by x-ray diffraction, scanning electron microscopy, infrared spectroscopy by Fourier transform and thermogravimetric analysis. The products of the synthesis are of interest because they can be used in different industrial applications.
