摘要：

The synthesis of NaY zeolite was carried out on fired kaolinite microspheres. Changes in porosity, chemical composition, and crystallinity of the solid show zeolite growth on both internal and external microsphere surfaces. It was also observed that, as a consequence of the alkaline treatment, the SiO2/Al2O3 ratio in the solid diminishes prior to the appearance of the zeolite, but increases when the zeolite begins to crystallize.
