Control of the size of the zeolite A crystals via varying of the hydrodynamic conditions

Alumosilicate hydrogels of the same chemical composition (aged for 0, 66 and 209 h) were treated hydrothermally under static and dynamic conditions at 80 °C. The end product was crystalline zeolite A with different crystal size distributions by volume and by number, but same morphology. The results indicate that the gel aging and different hydrodynamic conditions significantly affect zeolite nucleation and crystal growth.
