Sažetak
Thermal treatment of (NH4, Na)-exchanged Zeolites 4A and 13X results in the formation of an amorphous phase (below 1000 oC) and a crystalline phase of mullite at temperatures above 1000 oC. No structural changes are noticed for the (NH4, Na)-exchanged synthetic mordenite treated at the same conditions. Scanning electron microscopy (SEM), X-ray powder diffraction, Fourier transform infrared (FT-IR) spectroscopy and particle size analysis were used to characterize the initial materials and the obtained products.
