THE ANALYSES OF THE EFFECT OF HEAT TREATMENT ON THE STRUCTURAL PROPERTIES OF ZEOLITES FROM TURKEY USING FT-IR, MAS NMR AND XRD METHODS

Upon the heat exposure, natural zeolites show structural alterations which leads to a possibility to be used for different purposes in science and industry including building stones, concrete bricks and ceramic foam etc. The effect of heat treatment at 800 o C with different treatment times of 30, 60, 150 min of  clinoptilolite rich zeolites from Gordes region of Turkey were investigated by Fourier Transform IR (FT-IR), solid state magic angle spinning nuclear magnetic resonance (MAS NMR), and X-ray diffraction (XRD) spectroscopic methods. The obtained spectroscopic results indicated that rather than a total collapse, severe structural distortions occur for the investigated samples.
