Sažetak
Solid phase (gel) separated from freshly prepared sodium aluminosilicate hydrogel and the samples obtained during its hydrothermal treatment at 353 K was analyzed by different methods such as powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), Differential thermal gravimetry (DTG), High-resolution transmission electron microscopy (HR-TEM) and Atomic force microscopy (AFM). Analysis of the obtained results have shown that the freshly prepared gel is mainly composed of disc-shaped primary particles, but also of partially or even fully crystalline entities that act as nuclei for the further crystallization of zeolite.
