## Zeolite Y has been dealuminated with ammonium hexafluorosilicate. The influence of the reaction conditions -concentration of reactants, number of treatments, and time and temperature of reactionon the final properties of the products has been studied. The materials thus obtained have been char
Experimental evidence for two different aluminum-bonded silanol species, Si(OSi) (OA1)2OH and Si(OSi)2(OA1)OH, in a mildly dealuminated faujasite is presented. A sample of a low unit cell size (Si/AI=4.1) templated Y zeolite was prepared for this study to minimize interferences from framework struct
