Paper Title:
Structural and Morphological Transformation of NaX Zeolite Crystals at High Temperature
  Abstract

Well-shaped octahedral crystals of NaX zeolite of a large size of 30μm were synthesized by a hydrothermal method in a mother solution having a 3.5Na2O : Al2O3 : 2.1SiO2 : 593~2000H2O composition. Thermal treatment of NaX zeolite crystals results in the formation of an intermediate amorphous phase (T < 1000oC) and crystalline phase of aluminium silicate at temperature above 800 and 900oC. Environmental scanning electron microscopy (ESEM), High resolution Transmission Electron Microscopy (HRTEM), X-ray powder diffraction (XRD), Fourier transform infrared(FT-IR) spectroscopy, DTA/TGA and BET analysis were used to characterize the initial materials and the obtained products after various heat treatments.
