Abstract
The dependence of the surface Si/Al ratio in function of the volume Si/Al ratio was studied, for zeolite of type: A, X, clinoptilolite, mordenite and three samples of ZSM-5. Surface measurements were made by Auger electron spectroscopy (AES), and volume (bulk) measurements by atomic absorption spectrophotometry. It was found that the surface Si/Al ratio is identical with the volume Si/Al ratio. The dependence of the surface Si/Al ratio on the crystallization degree for zeolite ZSM-5 was also studied. We obtained some informations about the kinetics and mechanism of the crystallization process.Keywords
