Zeolite as a molecular sieve has attracted growing interest in many scopes of industry for their widespread applications in catalysis, adsorption, and separation processes, and finding new applications in electronics, magnetism, chemical sensors, agroindustry, biochemistry and medicine. These materials form in crystalline structure including channels and cavities with variety of pore sizes and shapes which cause applicability of them in such uses. The ion-exchange manner of zeolite prepare them as a usable material in filtration of dust, toxin removal, and as chemical sieves. Besides, considering this fact that zeolites have water as a part of their structure, after the water has been removed, other molecules are able to be placed in the structure, and therefore, zeolite can treat as a delivery system for the new molecules. This process has been applied in medicine for drug delivery, farm animal feed, and other research. In the other word, zeolite is the proper one for environmental and health care industries [1]. In this work, zeolite 13X has been synthesized in a hydrothermal process and characterized using conventional analysis apparatus to confirm zeolite structure. Comparing to some commercial zeolites 13X, our synthetic zeolite has been shown efficient properties such as proper surface area and excellent configuration of particles (size and shape). 2. Experimental – A molar ratio has been chosen to synthesis zeolite in a hydrothermal batch as follow: 3.5 Na2O: Al2O3: 2.9 SiO2: 150 H2O. The synthesis condition was carried out in a Teflon autoclave. hydrothermally with an overnight digestion time and an 8-hour crystallization time in an oven at 90°C. Some characterization analyzers have been applied such as XRD, SEM, and XRF to gain information on synthetic zeolite mentioned and compare with commercial zeolites.
