Phase Transition and Thermal Behavior Change of Low Silica X Zeolite at [Al]=90
Low silica X zeolite samples in the composition region of the number of Al atoms per unit cell ([Al]) between 84 and 96 were synthesized X-ray diffraction and nuclear magnetic resonance analyses of the obtained samples verify the existence of the phase transition point and confirm the changes in the thermal behaviors of the samples at [Al] = 90
