Sažetak
The structural and particulate properties of the solid phases, separated from the reaction mixture (12.5Na2O-8TPABr-Al2O3-60SiO2-4000H2O) at various stages of crystallization of zeolite ZSM-5, were characterized by X-ray diffraction (XRD), scanning-electron microscopy (SEM) and transmission-electron microscopy (TEM). The change of the concentration of Si in the liquid phase during crystallization was measured by atomic absorption spectroscopy (AAS). On the basis of the analysis of experimental results as well as the previously published experiences, possible mechanism of crystallization is proposed.
