摘要：

Hydrothermal synthesis of a NaAl zeolite from metakaolinite was studied at different values of the initial Al concentration, while the concentrations of the other components were kept constant. The role played by aluminum on the morphology and size of the crystals thus obtained was determined. Size becomes smaller, and the classic cubic morphology of the NaAl zeolite crystals changes to cubes with bevelled edges as the aluminum concentration increases.
